UNIX for Dummies Questions & Answers

Hi all,
I amd new in UNIX programming. I have a query.
I need to delete some files (like .dec files) from some folders. I have a list of folders. What will be command for it.
Please help me.

Thanks in Advance.

cd /folder
rm -f *.dec (will del all file with .dec)

or

rm -f filename (del one file)

Thx for reply but i have a list of folders from which i have to delete .dec files. How to delete from them at one time. any for loop or something has to be used??

for loop or while loop:


cat filename | while read line
do
cd $line
rm -f *.dec
done

I have a file in which i am having all folder name in diffrent lines. So accoding to you this command will work? Sorry i am asking again but i have to use this in live environment

let says, you have folder:

/tmp

and subfolders /tmp/test1 and /tmp/test1

content in your filename looks like this:

/tmp/test1
/tmp/test2

while loop will read line, and cd $line which means cd /tmp/test1 and rm -f *.dec in /tmp/test1, next, read next line

do it on test env first, or best advise, cp -rp /tmp/test1 /tmp/test1.bkup, just in case you screw up.

Why Not,

Use the find command. This is a very powerful command. Please use this to make sure you have the right files before running the second command. Obviously replace "folders" with the directory you are searching:

Code:

find /folders -type f  "*.dec"

Once you are confident that find has located the files, than run the below command.

Code:

find /folders -type f  "*.dec" -exec rm -f {} \; -print

HTH,
