Is it possible to substitute binary with same name alternative? I have /usr/bin/qtcreator
I want to use alternative version but /usr/bin/qtcreator is binary but not alternative.
What the way I should do this?
You could place your new qtcreator at /usr/local/bin/qtcreator, that location should have preference over /usr/bin.
You can check the possible locations for binaries and the order is which they are searched with echo $PATH and you can check which binary will be called with which qtcreator
In Bash:
$ alias qtcreator="/usr/local/bin/qtcreator"
or make sure the path to desired binary is mentioned before the undesired path in $PATH (... as mentioned by others).

I have a question if I want to create a file without using command or programming?
I know mkdir hi.txt, but is there any way to make without using these?
The touch PATH program will create an empty file at the location entered for PATH.
Example: touch /var/tmp/file.txt will create an empty file at /var/tmp/file.txt
If you want to create a file in Linux, without using any program/command,
you can use > this sign
like > hi.txt it will create a file

A very basic question here..
I have an executable redis-server at /home/dave/redis/src. Usually I cd /home/dave/redis/src then ./redis-server to execute it.
How can I call redis-server in the path? something like /home/dave/redis/src./redis-server
Thank you
You almost got it right. Except for the . (dot).
Instead of
/home/dave/redis/src./redis-server
Do
/home/dave/redis/src/redis-server
It is called an absolute path to the file, and it is simply the directories+file names, seperated by / (with a leading /, to make it absolute), so the . does not belong there.
/home/dave/redis/src/./redis-server
Use a dot in front of the first slash.
For example, if I want to open netbeans from the executable in /home/jason/IDE/netbeans/bin/netbeans,
I just put a dot in front of /home/.../.../ and the executable starts.

I have a directory in linux with lots of images having double underscore (__), I have to make it single under score (_). Lets say file name is a__1.jpg. I have to make it a_1.jpg. I have to do it for all files inside a directory. What should be the command?
Thanks
There are several ways to achieve this goal.
If you have mmv installed (or are able to install it), you can do
mmv \*__* \#1_#2
If not, maybe rename is an option:
rename _ __ *
(but alas, here I am not so sure about the syntax.)

I just switched my shell from bash to zsh and I noticed that zsh is not using same version of vim that I use in bash. Wondering why that might be the case? Do I need to set some config?
EDIT
remove other stuffs
You either have defined an alias for vim in one of them, or the value of the PATH variable is different.

I need help doing the following:
Say I'm in /usr/bin and I want to run the ls command on a subdirectory of bin called datafiles from within bin.
I need to locate all files using ls that contain a dot . and contain the letters f or u anywhere after the dot.
How do I do this?
Thanks
Is this what you want?
ls datafiles/*.*[fu]*
