I copied some files from a dos format to my linux machine. Now i have ^M at the end of the lines, and there are too many files for me to fix it manually. I also tried to use mtools and i still had a problem. Is there another way to convert dos text files to unix ?

I use vi * to edit all together, then do a search and replace on the ^M
character. The syntax in vi would be:

:%s/[ctrl-v][ctrl-m]//g

where the [] indicate key-presses, not actual typing. The line would read,
before you press enter:

:%s/^M//g

if you type it correctly. you type :%s/ and then type CTRL-V and then
CTRL-M (or just press enter), then type //g and it should look just like
the second example again. When you press enter, all instances of ^M will be
replaced with nothing.

You don't mention what OS release you're runninng. RH 7.2 has "dow2unix"
(Solaris has that too).

Emacs or vi can convert for you.

You can use "tr":
tr -d '\015' <infile >outfile
though you may want to put it into a script to simplify the renaming.

You can use perl to do the change and the rename
perl -pi -e 'tr /\r//d' FILENAME
or
perl -pi.bak -e 'tr /\r//d' FILENAME
if you want to save the original as a .bak.

I assume you are not real comfortable with tr, perl, sed, emacs or vi.

Probably the easiest way to do it is install the dos2unix rpm.

I usually use dos2unix with the -k option. From the man pages:

-k --keepdate
Keep the date stamp of output file same as input file.

Using sed, the stream editor:

sed 's!.$!!g' < infile > outfile.

This will substitute nothing on the last character of each line, therefore
removing the '^M'.

Good luck!

Try this perl script - I had the same problem and this works very well

#! /usr/bin/perl -w

while ($file = shift(@ARGV)) {
$new = $file.".unix";
die "file does not exist\n" unless (-e $file);
open(FILE,">$new");
@file = `cat $file`;
for (@file) {
s/\r//;
print FILE $_;
}
}

The command line is <thisfilename dos.txt> the output will be dos.txt.unix
with all the carridge returns removed
