$ type vim
vim is /usr/bin/vimcombine the output of 'alias' to 'grep' to find out all the 'ls' aliases:
$ alias | grep ls
alias la='ls -A --color=always'
alias ll='ls -lh --color=always'
alias lla='ls -lha'
alias ls='ls --color=auto'If you need to debug some unexpected alias and you want to know where it was set, there is no easy way.
The best way is to launch bash in verbose mode:
$ bash --verboseIt will output the content of all the files it sources. There is no easy way to grep the output.
In such situations, it would be nice to have the following:
- a simple list of files that bash sources upon start up.
- a precise indication of which file, which line a specific alias was set.
