Question

I’m trying to write a bash script which would locate a single file in the current directory. The file will be used later but I don’t need help there. I tried using ls and grep but it doesn’t work, I’m a newbie using bash.

#!/bin/sh
#Here I need smt like
#trFile = ls | grep myString (but I get file not found error)
echo $trFile

Answer 1

#!/bin/sh
#
trfile=$( ls | grep myString )
echo $trfile

The $( xxx ) causes the commands within to be executed and the output returned.
