Hi Folks,

I wanted to know if i can use RegEx in a for-loop of a shell script.
Here's a scenario, I have a set of files say x1, x2, x3..x9 in a directory(obviously with files other than this pattern). I want to append a line of text to all files that follow pattern x[1-9]. Can someone help me out? I know its simple. But i just cannot get it work.

for i in "x[1-9]"
do
echo hello >> "$i"
done

make sure you are in the directory that contains those files or use their absolute path.

cd $YOURDIR
for i in x?
do
echo "hello" >>./$i
done

Or this:

#!/bin/ksh
 
cd ${working_dir}
ls x[1-9] | while read file
do
  echo "hello" >> ${file}
done

Thanks. This one worked perfect.

The original solution is great; it just needs to lose the double quotes around the x[1-9] .
