Dear experts,

In a directory i have both *.TXT and *.txt files. I have a script-

for file in `ls *.txt`; do
mv $file /tmp/$file

How to list both .txt and.TXT file in one command so that script will move both .txt or .TXT whatever it find.

echo "$file_name"

well now how i will put the $file_name in my script--

for file in `ls *.[tTxXtT]*`; do
        mv $file /tmp/$file

please note that in my file i have *.txt.log. i must omit the .txt.log files. Only takes that ended with .txt or .TXT

for file_name in *.txt *.TXT
do
echo "$file_name"
done

should work fine
