Make this command better

JaredBusch

While I use Linux (Feodra) daily, I do not use rsync and sed every day.

I have a folder with two sub directories.
Each subdirectory contains files form two different PBX systems.
I wan to compare the filenames to get a list of things shared or only on a specific system.

This works, but I assume a could do it better.

rsync -n -a -i --delete newton/ edison/ | sed 's/*deleting  /only edison/g' | sed 's/>f+++++++++/only newton/g' | sed 's/>f.[.s]t....../on both    /g' | sed '/.d..t...... .\//d'

Output of rsync without the sed` tweaks:

[jbusch@lt-jared context_dump]$ rsync -n -a -i --delete newton/ edison/
*deleting   context_ivrSNOW
.d..t...... ./
>f+++++++++ context_ata-outbound
>f..t...... context_default
>f.st...... context_main

Output after sed

only edison context_ivrSNOW
only newton context_ata-outbound
on both     context_defualt
on both     context_main

Explanation of the bits:
List the diffrences: rsync -n -a -i --delete newton/ edison/
Delete means only on Edison: sed 's/*deleting /only edison/g'
Plus' mean only on Newton: 's/>f+++++++++/only newton/g'
File on both with different size or timestamp: sed 's/>f.[.s]t....../on both /g'
Just remove the empty directory line: sed '/.d..t...... .\//d'

What is this doing or not doing that you need it to do?

Better is not a useful qualifier! Better how?!

manxam

@JaredBusch : I'm not certain if this fits the bill, but what about the "diff" command? Of course, this does nothing to sync the files but does offer a way to simply compare the directories.

diff -rs manxam jaredbusch

This will get you :

Files /home/manxam/TEST and /home/jaredbusch/TEST are identical
Only in /home/manxam: i_am_manxam
Only in /home/jaredbusch: you_are_jared
