one question for bash shell script
Just one question for bash shell script.
In bash script, you can use *.txt to call any files in current folder that ends with .txt, like
rm *.txt
will remove all txt file in current folder.

My question is can you actually remember or use the file name among *.txt, I know file=*.txt will not do this if you call $file later.

Thanks!

You can use a for loop to iterate through the files

Code:
for f in *
do
    echo $i
    # do whatever you want with the file
done

You can use:
Code:
file=`ls *.nex`

Thanks a lot!

I tried this method before, but how could I do if I want to change a file among *.txt to *.exe (keep the first part while change the second part)?

Thanks!

i think this will help:-

read ext
#<enter the ext>
for i in `ls *.$ext`
do
echo $i
done

Thanks! This certainly works, but you have to type every time. So there is probably a way you do not need to type while can finish this?
