I have some directories with a number of "hidden" files. One example of this is I'm in a source controlled sandbox and some of the files have not been checked out yet.
When I hit TAB, I'd like the option of seeing these files.
A similar question has been asked before: CVS Tab completion for modules under linux
The answers to that question summarize to: "Ubuntu's got that built in".
I don't have the option of switching to Ubuntu, but surely I can use the same mechanisms.
how can I hook into the TAB-completion feature of tcsh to add additional file Support for CVS, SVN and BitKeeper would all be useful.
More important than support for a specific source control system is the ability to control the returned list myself.
An acceptable solution would also be to use a key-binding other than TAB. (ctrl- perhaps)
From the manpage:
the complete builtin command can be used to tell the shell how to complete words other than filenames, commands and variables
might get you started
I do not know how to program in tcsh. But if you can, then you could look at the file named "bash_completion" from the archive (find the download link here.)
On line 1673 begins CVS completion code - and this might be portable to csh if you are familiar with the differences between bash/tcsh.
On my ubuntu machine, there is also a section for SVN completion (in /etc/bash_completion) that doesn't seem to be present in the maintainer's archive.
That's not Ubuntu-specific behavior, it's the bash-completion project.
You could use that, if you can switch from tcsh to bash.

I want to create a shell script (naive version could be a simple alias), but I want to make it the good way from the bottom up. Writing script itself isn't a problem at all, but since it's possible a couple of other people would like to use this script as well I want to make it accessible and maintainable as well. That's why I have two questions:
Are there any guides regarding structure of the repository with shell script inside? I mean, some conventions that, for example, we put a script in some directory, manpage, should I split it into multiple files etc.
How to make this script be accessible to other people? I know that if we want to install command line tool, we move it to /usr/bin or /usr/local/bin, but what with docs or some dependencies?
There are a lot of tutorials regarding writing command line tools in Ruby or Python with some templates how to manage everything, but I haven't found anything about writing a command line tool as a shell script.
In general, you would follow the conventions in man hier for the distribution. A shell script would be treated the same as a binary file.
I have a program, let's call it exampleProg, in my /opt directory, and I want to run it from any directory, rather than just:
/opt/radFolder/exampleProg
This should be a simple task, I've done it several times before on different computers. I've searched around, and found instructions ranging from:
edit .bash
edit .bashrc
edit .profile (Another stackoverflow answer said that, while this worked at one time, it no longer functions.)
edit /etc/environment/
with PATH="$HOME/bin:$PATH:/opt/radFolder/:" or just adding the /opt/radFolder bit.
Yet none of them seem to work. The problem that I'm running into is that there doesn't seem to be a yet there doesn't seem to be a universally agreed-upon solution. I've tried so many that I think one of my changes has prevented the appropriate one from taking effect. Would someone help me put this to rest once and for all? Many thanks in advance.
I'm running ubuntu 14.04 LTS x64.
First, understand that writing things to those files does not mean everything is instantaneously, and globally, changed. In fact, nothing is changed until the file is sourced (via . or source), and even then, the environment changes apply only to the current shell (and subsequent created children, if export is used).
INVOCATION, near the top of man bash, spells out which files are automatically sourced when. To summarize:
~/.bashrc is read for new non-login, interactive shells, e.g., when you open a GUI terminal. On many systems, this file by default in turn sources /etc/bashrc.
/etc/profile, ~/.bash_profile, and ~/.profile are read by interactive login shells.
Adding to ~/.bashrc should be effective, but it will only work for subsequently invoked, interactive, non-login shells (and their children, if $PATH is exported). However, since it's prone to being sourced repeatedly, using it to add to an existing variable (as with $PATH) can produce repeated concatenations (see here).
An issue with the second category, .profile, is that if you use a GUI login, the display manager may not source it, but it logs you in, meaning, you never invoke a login shell and hence none of those is ever sourced. If this is the case, sourcing them from ~/.xsession should work (this has a system wide correlate in /etc/X11).
I often find myself taking a lot of time to navigate through my filesystem when using the linux shell. This generally occurs because the autocompletion of bash only works if you provide the start of the file/dirname. What I often end up in is a lot of 'ls' with 'grep' commands, finally doing a 'cd'.
When you use a GUI based filebrowser (like Nautilus) you can type any part of a file/dirname and it will have matches that it jumps to directly. This makes it a lot easier and faster to navigate.
I wonder if anybody knows any great tools that helps with this problem. I know of the existence of Midnight Commander, though I never really used it for real and I couldn't figure out a direct solution for my problem the first couple of times I tried it. Also it seems not suitable because I want to have my shell's current working directory to be changed so I can do stuff there, instead of being stuck in an external program like Midnight Commander.
Try autojmp
https://github.com/joelthelion/autojump
And following article provides another solution
http://jeroenjanssens.com/2013/08/16/quickly-navigate-your-filesystem-from-the-command-line.html
You can first use the autocd or autopushd in zsh. You would just have to type the directory you want to go to, without the hassle of typing cd or pushd everytime.
You also have the globing possibility. For example, if I got those file in a directory:
1-a.tar
1-b.tar
c.tar
I can just type
*a.tar
without caring about the beginning of the file.
As a last solution you can always use an alias to the find command with a personalized option.
So I was hoping that some old school Vim'ers could help me out. These are all separate questions and normally I would put them up each on their own but I'm not sure if that qualifies as question whoring here.
Plus I think if you know enough to be asking any of these questions they will all be coming up in the near future:
I have a library I'm writing and a series of applications that use that library. There doesn't seem to be an easy way(from what I can tell) to build a ctags file for the library and build one for each of my applications and make sure one references the other when I'm in vim.
Using gf to open files from command mode is awesome, but a lot of my include files
don't contain the full path. They refer to an include directory I set in the IDE. How can I set this directory as another point for Vim to start looking for files?
Is there a way to compile a file inside Vim and send the output to a buffer? I'm currently using MSVS 2k3 but I'll be porting over to Linux in a few weeks so if this is possible on either system I'd appreciate it.
Re 3)
If you put a makefile in your root dir, you can simply write
:make
This will run make and (iirc) put any errors into a seperate buffer, and make vim goto the first compile error. From there you can navigate all erroring lines using :next-error
Also, see this page
http://wiki.beyondunreal.com/Legacy:Vim
and
http://linux.byexamples.com/archives/287/perform-grep-and-make-in-vim/
for details on how to show the result in a seperate console.
1- tags files are independent, and can be used together. See :h 'tags'
I can't tell what is the easy way to build tags files. I have one that consists in using two plugins of mine:
one (draft) plugin that knows how to update C++ tags files (it should be easy to adapt it to other filetypes),
and another (local_vimrc) that helps me define directories-local .vimrc. Thus for any files within a given directory hierarchy, I can adapt the &tags options to use the relevant tag files, and the current tag file that will be rebuilt automatically (or when a keybinding is triggered). (Plugins like project should do the trick as well)
2- :h 'path'
3- :h :make
HTH.
2)
:cd {path}
For help:
:he cd
A few others like :lcd might be better suited. Just scroll down that help page.
This is rather off topic, but might still be useful: if you're using Visual Studio a lot and like Vim, you might want to look at ViEmu. It's the best Vim-emulation for any IDE I've yet seen, and the cost is really low. :) And no, I'm not getting a commission. :P
It's not obvious, but if you open a directory instead of a file, it's nicely browseable.
e.g.
:e . (colon-e-dot)
:e .. (colon-e-dot-dot)
will let you browse from your current directory or its parent.
(understanding that you were probably hoping for a capability to have vim accept e.g.
:e abc.txt
and have it look in several directories, which I don't know how to do.)
It needs to be graphical. No sed, awk, grep, perl, whatever. I know how to use those and I do use them now, but I need to cherry-pick each replace in 300+ files.
I want a tool where I can:
type a search string
type a replace string
select a directory and file extension
and it would recursively go into each file in that directory and its sub-directories, open it and scroll to the place where search string is and offer two options:
replace (and find next)
find next
Nothing more. Reg.exp. support is a plus, but not required.
SOLVED: Regexxer is exactly what I needed. In case someone needs it on Slackware, here's what you need to download and how to compile it (choosing correct version of each dependency can be a PITA)
I think regexxer is exactly what you're looking for:
Regexxer
regexxer is a nifty GUI search/replace tool featuring Perl-style regular
expressions. If you need project-wide substitution and you’re tired of
hacking sed command lines together, then you should definitely give it a try.
See also the screenshot, looks a lot like what you're describing:
Emacs + dired + query-replace-regexp
For complete recipe follow this link (it's rather long, covering all possible alternatives),
jEdit does exactly what you need. It is written in Java and works well in Linux, Windows and OS X (probably other operating systems also).
Lately Kate (if you use KDE) can do it, but in a very tricky way. Go to "Edit>Search in Files", and choose the folder within which your files exist.
The trick is that only after the search results appear, you will find a text box and a button called "Replace checked". This button will do what you want.
I use gVim for this task all the time. I open up all the files at once, then use the commands to perform a subsitution on each file, asking for confirmation. Generally I use < 20 files, so I open them as tabs and use this:
:tabdo %s/foo/bar/gc
gVim works fine on Windows :) My coworkers often use Textpad to do this same thing, but I'd say gVim is much more efficient at it.
If you are a KDE user there's also kfilereplace.
