I have a few files to be backed up. I need a script to check line number of a file and if it exceeds, say 8000 lines, it will simply zip it and name it with date prefix format.
I need your help.
This script will get the line numbers, then if it is more than 7999 (greater than or equal to 8000) it will make a .tar.gz of the file.
#! /bin/bash
lif=$(wc -l < /home/USER/path/to/file.txt)
if [ "$lif" -gt 7999 ]; then
tar /home/USER/path/to/where/you/want/the/backup/to/be/filename-$(date +%Y-%m-%d-%H:%M).tar.gz /home/USER/path/to/file.txt
Don't for get to chmod the script to get it to run - chmod +x /home/USER/path/to/script.sh
The cron command would be 0 17 * * * /home/USER/path/to/script.sh to run every dday at 5pm. Use this generator to help get the cron command if you want it to be different.
Thanks @Jnuk for the generator!
