When trying to get to know a new system I really like the ‘tree‘ command. It gives me a fast and nice overview of the filesystem of the application. Sometimes I work on systems that does not have this great tool available and for those occasions I made this bash script:
#!/bin/bash
olddir=$PWD;
declare -i dirdepth=0;
function listfiles {
cd "$1";
for file in *
do
for ((i=0; $i < $dirdepth; i++))
do
##Tab between each level
printf "\t";
done
## Print directories with brackets ([directory])
if [ -d "$file" ]
then
printf "\1[$file]\n";
else
printf "$file\e[0m\n";
fi
##Work our way thru the system recursively
if [ -d "$file" ]
then
dirdepth=$dirdepth+1;
listfiles "$file";
cd ..;
fi
done
##Done with this directory - moving on to next file
let dirdepth=$dirdepth-1;
}
listfiles "$1";
##Go back to where we started
cd $olddir;
unset i dirdepth;
To use the script just do the following:
- Create a new file called 'tree.sh' (or whatever you like)
- Paste the code into the file and save
- Make the file executable
- Run the file: . tree.sh
This script is tested on OSX 10.6.8, Red Hat Enterprise Linux AS release 3 (Taroon Update 9)
