My code is :

#!/bin/bash

strversion=`apache2ctl -v | awk '{print $3}' | sed  's/(Debian)//g;s/Server//g;s/built//g;s/2022-06-09T04:26:43//g'`

echo ${strversion%}
exit 0

i get this:

Apache/2.4.54

but i will have to look

Apache version 2.4.54

CodePudding user response：

That's because the variable expansion is not quoted. An unquoted variable is subject to Word Splitting (and Filename Expansion)

echo "Apache2 - ${strversion%')'}"
# ...^...........................^

@glenn jackman

i add this to the end

sed 's/\// version /g'
