Most of the times you create/place a script on/from Windows or WinSCP to a Unix machine without using vi command you will most likely encounter the errors below.
From what I saw it always happens because of special characters that look like simple space but are preformatted from Outlook or other tools.
Errors Encountered:
ksh:
0403-015 Cannot access a required executable file. It is in use.
bash:
/bin/bash^M: bad interpreter: Cannot Open or Remove a file Containing a Running Program
Place your script on a Linux machine and run the following command:
sed -i -e 's/\r$//' Your_Script.sh
Command Explained:
sed
stream editor for filtering and transforming text
-i[SUFFIX], --in-place[=SUFFIX]
edit files in place (makes backup if extension supplied)
-e script, --expression=script
add the script to the commands to be executed
Upload the script in WinSCP using the "Text" mode.
See https://winscp.net/eng/docs/transfer_mode
You better enable the "Automatic" mode, instead of explicit "Text", so that you won't laster inadvertently upload binary files like images using the text mode.
New to Cygwin and trying to launch the batch file from the current working directory. I've done similar things before for .exe files in Windows 10 using the Registry Editor (see link):
https://www.windowscentral.com/how-launch-bash-shell-right-click-context-menu-windows-10
My Cygwin.bat file looks like this:
#echo off
SETLOCAL
set HOME=C:\path\to\home
C:
chdir C:\cygwin64\bin
bash --login -i
ENDLOCAL
However, when I right click on a directory in order to "Open Cygwin.bat here", the terminal opens at C:\path\to\home. How can I make sure the terminal opens in the current working directory?
To obtain the expected result you need to use the chere package.
chere -i
is usually enough to create a proper Bash Prompt Here entry in Explorer left mouse button menu.
Please note that the usage of the cygwin.bat is not recommended anyway as does not use mintty as terminal
I use phpstorm and it's terminal facility.
In terminal section I typed F:\Projects\cygwin64\bin\mintty.exe -i /Cygwin-Terminal.ico - so it uses Cygwin as terminal. But it opens it in home folder. Is it possible to open it in different folder? By typing a command or by doing something else.
Because I have a folder called F:\Projects\Local in this folder I have vagrant and I want to open phpstorm, open terminal within php storm and just type vagran up. I don't want to open cgywin again.
thanks
If you just want to open Cygwin with Mintty in the project directory then you can execute the command:
F:\Projects\cygwin64\bin\mintty.exe /bin/env CHERE_INVOKING=1 /bin/bash -l
This will avoid automatically changing to the home directory. See https://code.google.com/p/mintty/wiki/Tips#Starting_in_a_particular_directory for more information on this command.
If you want to use the embedded PhpStorm terminal, then you can modify the Shell path in the terminal settings. Open File > Settings... > Tools > Terminal. Replace the shell path with F:\Projects\cygwin64\bin\env.exe CHERE_INVOKING=1 /bin/bash -l. You may need to restart PhpStorm after this change.
Note: this is assuming that your Cygwin Root Directory is F:\Projects\cygwin64\.
For whome the above way ain't work anymore, like in PhpStorm v. 2016.3. The shell path have to be enclosed in quotes
"C:\Users\MyUser\.babun\cygwin\bin\env.exe" CHERE_INVOKING=1 /bin/zsh.exe
For the PhpStorm that I'am using (v10.0.4) in Windows 10 I use this command works:
D:\tools\.babun\cygwin\bin\env.exe CHERE_INVOKING=1 /bin/bash.exe
I'm using Babun which installs the Cygwin in D:\tools\.babun\cygwin.
I am sending a .sh file created from a windows machine to a linux so that I could run it there. The problem is that I keep on getting an error called bad interpreter.But when I program the shell script in the linux machine it runs with no problems even though it has the same code with the one sent from the windows machine. After my ivestigation, I found out that the windows machine .sh script is a text/plain file(using file -bi) and the other one from the linux machine is a text/x.shellscript. Is there a way to convert the text/plain to a text/x.shellscript? thank you
this is the script:
#!/bin/bash
date
sudo apt-get update
I tried a solution by doing another .sh file in a linux box containing only
#!/bin/bash
Then the windows machine only sent a file containing test commands like :
date
hostname
Then I append the file from the windows box to the linux one with
cat windows.sh >> linux.sh
It did not work if I run linux.sh. It says errors like:
./linuxh.sh: line 2 $'date\r':command not found
./linuxh.sh: line 2 $'hostname\r':command not found
However, if I open Linux.sh then save it again without doing anything. It works
I'm summarising below the steps you need to take so other users can see easily what needs doing:
Firstly, you need to check your script has the correct path to your interpreter after the "#!" in the very first line. This is should probably be:
#!/bin/bash
or
#!/usr/bin/bash
and you can find which is correct by typing:
which bash
on your Linux box.
Secondly, you need to make sure that any Windows carriage returns (or "^M") at the ends of the lines are removed before expecting your Linux box to run the script. You can do this with:
dos2unix yourscript
Just for reference, you can easily see weird characters such as TABs or linefeeds or carriage returns in Linux by using:
cat -vet yourfile
or
sed -n l yourfile
Thirdly, you need to make sure your script is executable on Linux, using chmod like this:
chmod +x yourscript
Finally, when you have done all that, you need to either add the directory where the script is located to your PATH variable (and export it) or give the full path to your script like this if your script is in the current directory:
./yourscript
or like this if it is located somewhere else
/some/directory/some/where/yourscript
Whenever I start my console gnome-terminal in Ubuntu, it starts in the home directory. How can I make it start in a different directory say ~/myfolder?
I tried to write cd ~/myfolder in ~/.profile but nothing happens.
If you start gnome-terminal like gnome-terminal --working-directory=myfolder it will start with the working directory at ~/myfolder so you could add a new entry to your menu to use that command instead of the other one.
I did this way - with script:
open 3 tabs in the same window size 170x40, each "tab" starts in a different directory.
gnome-terminal --geometry=170x40 --working-directory=myfolder1 \
--tab --working-directory=myfolder2 \
--tab --working-directory=myfolder3
Add the following to your ~/.bashrc
cd ~/myfolder
You could use the nautilus-open-terminal extension. This allows you to right-click on a folder in nautilus and open a terminal window with that directory as its working directory.
You can also run a terminal in the normal way, type "cd ", and drag a folder icon from nautilus to the window. This will paste the path of the folder into the command line and you then type return to change to that directory. You can do the same thing with regular files to paste their path and run commands on them.
Directory option
There is the option --working-directory to specify the startup directory of the terminal (no short option form).
The basic approach to open the terminal in /some/dir is
gnome-terminal --working-directory=/some/dir
but there is a trap...
Bad trap
Assuming we want to start the terminal in the directory ~/dir.
This does not work:
gnome-terminal --working-directory=~/dir
The command looks perfectly fine according to the option syntax, but the terminal starts in the home directory.
It's because it does not expand the tilde (~), for confusing reasons - see below.
Thesse do work:
gnome-terminal --working-directory=/home/auser/dir
gnome-terminal --working-directory=$HOME/dir
gnome-terminal --working-directory ~/dir
Tilde expansion
Note there is no = in the last variant. Because of this, the ~ is at the start of a shell word, and therefore is handeled by tilde expansion.
The problem is that ~ does not get expanded everywhere, but only in certain places. One of them is in variable assignments, like directory=~/dir. That's ok, ~ gets expanded to $HOME, but --working-directory=~/dir does not expand ~, because that is not a variable assignment, it only looks very similar.
Actually, this is how I turn it off for everyone by default.

From GNOME Terminal - Getting Started:
You can also specify a command that runs automatically when you start GNOME Terminal in the profile.
If the folder has a complicated path, ie not just ~/myfolder, you could create a symlink to it in your home directory so you can get to it quickly. You can also set the CDPATH environment variable to tell bash to search a list of directories when you type cd myfolder.
To open in my desired directory as root user I ran:
gnome-terminal --working-directory=/home/my-project/ -x bash -c "sudo su"
I'm impressed by
Neil's Mayhew comment
and
Volker's Siegel answer. I've tried to not only set default directory for
gnome-terminal but preserve habitual behavior of desktop environment as well (I'm using Linux Mint 17.1 Cinnamon,
GNOME Terminal 3.6.2, perhaps it also can be applied for other Gnome-congenered DEs). So let me put my two cents in.
Adding cd ~/myfolder at the very end of ~/.bashrc does the job. But as already mentioned it will affect every
interactive shell. Even more, if you open some directory in a file manager (Nemo or Nautilus or something like
this) and appeal to the context menu from there (e.g. right click and then select Open in Terminal) new instance of
gnome-terminal will be started in ~/myfolder regardless of the folder which was loaded in the file manager.
Even if you run gnome-terminal --working-directory=/some/other/folder explicitly it will still open ~/myfolder. Seems that the
approach with .bashrc is unusable.
gnome-terminal --working-directory=myfolder works fine but only when you use custom menu entry in you DE
(or custom shortcut on desktop) which runs terminal with this parameter. If you would like to run gnome-terminal from command line
or from mini-launcher (press Alt + F2), you have to type the parameter every time. Anyway this approach is more-or-less usable.
How gnome-terminal determines which folder to open? When --working-directory is not specified it opens current
working directory (e.g. $PWD) otherwise it opens directory specified explicitly.
I've found the following solution.
Create a file named gnome-terminal in your ~/bin folder. It will act as shortcut but from everywhere (start menu,
mini-launcher, other terminal instance, etc) because ~/bin is already in $PATH (at least in Linux Mint...). Make this file
executable. Then put the following content into the script:
#!/bin/bash
home_directory=~
if [ "$PWD" == "$home_directory" ]; then
# When 'gnome-terminal' was ran from either
# - start menu
# - mini-launcher
# ...
# parent directory is set to $HOME.
#
# We respect original command line arguments.
# For example, when terminal is ran from another
# terminal instance and '--working-directory' is
# specified explicitly we should left it as it is.
# If there are two '--working-directory' switches
# in the command line 'gnome-terminal' will pick up
# the last one.
#
# Also we use full path to executable here in order
# to prevent recursive calling of 'gnome-terminal' from
# '~/bin'.
/usr/bin/gnome-terminal --working-directory=/ "$#"
else
# 'gnome-terminal' was from another directory.
# We don't change anything.
/usr/bin/gnome-terminal "$#"
fi
If you run gnome-terminal from start menu you will see that current folder in new terminal is / (you can use any folder, for example, ~/myfolder because our custom wrapper is a Bash-script, so shell's expansion with work fine).
If you appeal to Open in Terminal in a file manager you will get current directory in the new terminal.
If you run gnome-terminal with explicit --working-directory parameter (perhaps, from existing terminal instance) new terminal instance will be opened in the directory you specified.
