This is a very short tip.
I made a small shell script to delete and create a link to my localhost htdocs directory. That way, I never have to move my projects around, I just keep them in separate directories under one main directory.
The problem comes when I forget important things: such as directory names. Instead of just typing ls /projects, I want the script to tell me the options I have.
And so, this little code is born, by not giving the script any arguments:
#!/bin/bash
if [ -z $1 ]
then
echo "No valid user was provided!"
echo "Possible users:"
declare -a FOO
let count=0
let count2=0
for d in $( find /projects -maxdepth 1 -type d -printf "%f " ); do
if [ $count2 -gt 0 ]
then
FOO[$count]=$d
fi
((count++))
((count2++))
done
echo ${FOO[@]}
fi
Note: I did it this way because otherwise you get “projects” in the list of results.
