Removing M^ from multiple files

deaconf19 · #1 (**permalink**) 11-15-2007

to do this i usually type dos2unix <file> -o <file>
and this will remove the M^ from the end of each file. well i have over 100 files that someone copied that i need. how do i remove the M^. i saw a perl script but i am not familiar with .pl at all really

Perl not needed.

Try it in a test area first.....

Code:

#!/bin/sh

find directory -type f | while read N
do
          if dos2unix "$N" -o "$N".tmp
          then
                 mv "$N".tmp "$N"
          fi
done

sorry i just reread my post. i meant within the file there is the ^M not on the extensions.

That is because "directory" is supposed to be replaced by the directory you want to make the changes in.

As a general idea, if you are offered a script that you don't understand what it's doing, don't run it, ask what a part of it is doing. Otherwise people could tell you to run all kinds of rubbish.

Just to pass on snippets, here's what I use:

perl -pe 's/\015\012/\n/g' - dos to unix -- just pipe through it
perl -pe 's/\n/\015\012/g' - unix to dos -- just pipe through it

cat filename |perl -pe 's/\015\012/\n/g' > filename.without.ctrl.m

dos2unix works well, but isn't on all systems. I now use this perl.
