get the perl version (decimal value comparision)
Hi All,
can you pls throw some light for below logic

-> Check the perl version
-> if the version is greater than or equal to 5.8
-> proceed to next step
-> else fail

Regards

How about this using bash:

Code:
#!/bin/bash
IFS=' .v' V=( $(perl --version) )
[ ${V[3]:-0} -le 5 ] && [ ${V[3]:-0} -ne 5 -o ${V[4]} -lt 8 ] && exit 1
echo "Perl version ${V[3]}.${V[4]}.${V[5]} is acceptable"

Or with ksh:
Code:
#!/bin/ksh
OLDIFS=$IFS
IFS=' .v'
set -A V $(perl --version)
IFS=$OLDIFS
 
[ ${V[3]:-0} -le 5 ] && [ ${V[3]:-0} -ne 5 -o ${V[4]} -lt 8 ] && exit 1
echo "Perl version ${V[3]}.${V[4]}.${V[5]} is acceptable"
