awk -Search pattern through Variable
Hello,

We have wrote shell script for multiple file name search pattern.
file format: <numner>_<20180809>.txt
starting with single number and ending with 8 digits number

Command:
Code:
awk -v string="12_1234" -v serch="^[0-9]+_+[0-9][0-9][0-9][0-9]$" "BEGIN{ if (string ~/serch$/) print string }"

If sting matches then return value.

Try
Code:
awk -v string="12_1234" -v serch="^[0-9]+_+[0-9][0-9][0-9][0-9]$" "BEGIN{ if (match (string,serch)) print string }"
12_1234

Try this adaptation to your command in post #1:
Code:
awk -v string="12_1234" -v serch="^[0-9]+_+[0-9][0-9][0-9][0-9]$" "BEGIN{ if (string ~ serch) print string }"
