Re: [suse-linux-uk-schools] dos2unix, error messages...why???

Hello Damian, Thankyou ever so much for that perl script :-). I shall test it on my laptop. I had written a similar utility in sed and awk, but it looks as though your perl one is much quicker. I really should start programming in perl again. Thanks Again, Thomas Adam Linux Co-ordinator at The Purbeck School (Network Support) Purbeck School, WAREHAM, Dorset, www.purbeck.dorset.sch.uk ----- Original Message ----- From: Damian Counsell To: SUSE Sent: Thursday, June 28, 2001 1:53 PM Subject: Re: [suse-linux-uk-schools] dos2unix, error messages...why???

Thomas!

Is this any use?

#! /usr/local/bin/perl

# dos2unix.pl by David Efflandt # Modification of script from "Learning perl" p.353 # O'Reilly & Associates, Inc. # # Run after transfering text files from DOS to UNIX system. # Strips carriage returns from DOS files for use UNIX. # Transfers file permissions to new file (except suid bit). # # Usage:\tdos2unix.pl FILELIST # where FILELIST = one or more filenames # # If you edit this file in DOS you can run it on itself by typing: # perl dos2unix.pl dos2unix.pl # # Modify variables below for other search and replace functions.

$find = "\r"; # find this $sub = undef; # substitute with this $rm_bak = 1; # remove old file after conversion: 0 = no, 1 = yes

while (<>) { if ($ARGV ne $oldargv) { ($dev,$ino,$mode,$nlink,$uid,$gid) = stat($ARGV); $backup = $ARGV . '.bak'; rename($ARGV, $backup); open (ARGVOUT, ">$ARGV"); chmod $mode, $ARGV; select(ARGVOUT); $oldargv = $ARGV; } s/$find/$sub/; } continue { print; if (eof) { print STDOUT "Converted: $oldargv\n"; unlink $backup if $rm_bak; } } select(STDOUT);

or this?

#!/bin/sh

es=1 if [ $# -eq 0 ] ; then exec tr -d '\015\032' elif [ ! -f "$1" ] ; then echo "Not found: $1" 1>&2 else for f in "$@" ; do if tr -d '\015\032' < "$f" > "$f.tmp" ; then if cmp "$f" "$f.tmp" > /dev/null ; then rm -f "$f.tmp" else touch -r "$f" "$f.tmp" if mv "$f" "$f.bak" ; then if mv "$f.tmp" "$f" ; then rm -f "$f.bak" es=$? echo " converted $f" else rm -f "$f.tmp" fi else rm -f "$f.tmp" fi fi else rm -f "$f.tmp" fi done fi

exit $es

all the best

Dear List,

I am trying to use 'dos2unix', but I am finding that each time I try it, I get the following error message:

recode: /doc.txt failed: Ambiguous output in CR-LF..data

Does anyone know what causes this, and how I fix it.

In fact, the command 'dos2unix', is a shell alias, for the following:

'recode ibmpc..lat1'

This is doing my head in!! I am very tempted to write a sed script instead, but I thought I'd ask the list first!!

Regards,

Thomas Adam
