hi all,

I copied set of files from a linux machine to an aix machine but in binary mode copy , ASCII mode copy both leed to control M charecters in most of the files.
Any shell script/C script to remove control M charecters in all files in a given directory.

Pls reply if you are aware of the solution ASAP.

Code:

sed 's/^M//g' input_file > $$Temp
mv $$Temp input_file

Where '^M' is entered as 'ctl-V' and 'ctl-M'.

perl -p -i -e 's/^M$//' *

or

Hi aigles,

Your script worked for me..but only for files in a single directory .It is not going to subdirectories.Could you please tell me how to do this recursively.

Thanks in advance

Adapting aigles' code

Code:

for file in $(find /path/to/dir -type f); do
   tr -d '\r' <$file >temp.$$ && mv temp.$$ $file
done
