I need to know how what command or commands I can use in a bash script that would give me a directory listing like this (note the extra lines at the end).

Total bytes:    17899
Total files:    4
Directories:    9
And scripts:    1

The standard ls command cannot do this so I’m wondering what I can use in my bash script to achieve this.

    The base command you want to use is ls -l but you’re going to need to post-process the output to get those last four lines.

    For example, here’s one that will get you the first three items plus the fourth which I’ve assumed is the number of regular files with the execute bit set for the owner:

    #!/usr/bin/bash
tmpfile=/tmp/tmpfile.$$
ls -l | tee ${tmpfile}
echo
echo "Total bytes:" $(awk '{sum += $5} END {print sum}' ${tmpfile})
echo "Total files:" $(grep -v '^total ' ${tmpfile} | grep -v '^d' | wc -l)
echo "Directories:" $(grep -v '^total ' ${tmpfile} | grep '^d' | wc -l)
echo "And scripts:" $(grep -v '^total ' ${tmpfile} | grep '^-..x' | wc -l)
rm -f ${tmpfile}

    which outputs:

Total bytes: 1624999
Total files: 2
Directories: 13
And scripts: 1

    However, I’m not entirely sure how you’re deciding what a script is. If it’s different to what I assumed, it’s still doable, you just have to figure out what the actual command is (tell us what you want to measure to get the value).
