I'd like to create alias by script, and use it in bash.
Namely:
#!/bin/bash
alias mycmd="ls -la"
Bash:
login@host ~$: ./script
login@host ~$: mycmd
*ls output*
Of course, alias should be available just for one session (not .bashrc etc). Is it possible? Unfortunately I have not found a solution.
login@host ~$: . ./script
login@host ~$: mycmd
Will execute it in your shell I believe.
The proper way to do is to source the script rather than running it.
source myscript.sh
mycmd
Create a script to do the job, and put it in a bin directory on your PATH (probably $HOME/bin):
$ echo "exec ls -la \"\$@\"" > $HOME/bin/mycmd
$ chmod 555 $HOME/bin/mycmd
$
This is utterly reliable if you actually set PATH to include $HOME/bin.
(Of course, we can debate the merit of typing 5 letters instead of 6 characters, but I assume the names are illustrative rather than real.)
