Where can I find a list/file of all aliases created in Ubuntu 17.04? I mean shortcuts for commands most frequently used and more.

List of defined aliases
Type alias, you'll get a list of all defined ones in your environment.
$ alias
alias l='ls -CF'
alias la='ls -A'
alias ll='ls -alF'
alias ls='ls --color=auto'
List along the file they've been set in
To find the files that your aliases have been defined in, use this solution, with a little bit altering it:
$ PS4='+$BASH_SOURCE> ' BASH_XTRACEFD=7 bash -xl 7> /tmp/mylog
$ grep "alias " /tmp/mylog | grep -e /home -e /etc
Which gives you a list of files, stating what alias defined there, the output is similar to:
++/home/ravexina/.bashrc> alias 'la=ls -A'
Which states 'la=ls -A' has been set in my .bashrc.
Important files
There are many places that we can define our aliases, the most important ones might be:
- Standard ones:
~/.bashrc~/.bash_aliases
- One of them in order:
~/.bash_profile~/.bash_login~/.profile
- Works but not a good place, unless you want it system wide:
/etc/bash.bashrc/etc/profile
And any other place which get sourced while running a shell.

Witch one of the 'important files' is the best one to add a function instead of an alias? If there is one.– glc78Aug 12, 2017 at 13:36

1That would be
~/.bashrc, However what I suggest is to create a new file:~/.bash_functionsand put all functions there, then source that file in your.bashrclike:. ~/.bash_functions.– Ravexina ♦Aug 12, 2017 at 13:58 -
Before your answer I just created the file
.bash_profileand added to.bashrc. I'm going to rename the file as suggested.– glc78Aug 12, 2017 at 15:18 -
1Remember if you use a file named
.bash_profilethen your.profilewill not going to be sourced any more... ;)– Ravexina ♦Aug 12, 2017 at 19:42 -
Aliases are defined on a per-user, per-shell basis. You can see what aliases are defined for your current shells via
alias
Read more about aliases in man bash.

I might also throw in that the .bashrc for new users (not existing) is populated from /etc/skel/.bashrc, inside which you'll find aliases for things like ll, la, l, etc. So if you want every new user to have more/less/different aliases that's the place to modify them
