Shell Programming and Scripting

Hello again,

I've changed the script to use an AWK statement instead and I kind of got it to work, but I'm still getting some errors along with correct returns. This is what I have so far (I put an asterisk on the end of 'scripts' because I have copies of the same 4 backup scripts (only '.bkp' extension for now) in 2 folders: 'scripts' and 'scripts2'):

mDirs=”/dir/dir/dir/scripts*”
mFiles=`ls ${mDirs}`
for file in ${mFiles}
do
mExt=`echo $file | awk ‘BEGIN { FS “.” } $NF ~ /O$|bkp$/ {print $NF}'`
if [ ${mExt} = ${file} ]
then
echo ${mExt}
fi
done

I set it up to return from 2 directories, 4 files each. This is what it is returning:

ksh[4]: test: argument expected
ksh[4]: test: argument expected
file1.bkp
ksh[4]: test: argument expected
file2.bkp
ksh[4]: test: argument expected
file3.bkp
ksh[4]: test: argument expected
file4.bkp
ksh[4]: test: argument expected
ksh[4]: test: argument expected
file1.bkp
ksh[4]: test: argument expected
file2.bkp
ksh[4]: test: argument expected
file3.bkp
ksh[4]: test: argument expected
file4.bkp


Any ideas on what I'm doing wrong?

Code:

mv /dir/dir/*/scripts/*.+(kshO|bk?(u)p|?(_)OLD) /dir/dir/staging

Thank you everyone!

I figured out why I was getting my error, I needed double quotes around the variables in my if statement:

if [ "${mExt}" = "${file}" ]

Still learning I guess - I forgot about the arithmetic thing (if it's not arithmetic, it should be in quotes).

Thanks ShellLife for all your time and great ideas, and thanks Radoulov for that final piece - I was going to do it a different way but now I see that wouldn't have worked, your way is better!
