Question

Consider I have a file abcde.txt which may contain one or more lines of text. I want a script that will DELETE the file if it contains single line.

Something like, if 'wc -l abscde.txt' = 1 then rm abscde.txt

My system : Solaris

Answer 1

Here’s a simple bash script:

#!/bin/bash

LINECOUNT=`wc -l abscde.txt | cut -f1 -d' '`

if [[ $LINECOUNT == 1 ]]; then
   rm -f abscde.txt
fi
