Hi,

recently i have experienced weird problem using dos2unix. seems like converting process looks ok, but renaming tmpfile to outfile has problem like below.

Code:

root@myConsole:/data/customer.cfg/dbmtdpps/work_dir.dpp # /usr/bin/dos2unix pesc.add /tmp/pesc.add
dos2unix: converting file pesc.add to UNIX format ...
dos2unix: problems renaming './u2dtmp8jwsge' to 'pesc.add'
          output file remains in './u2dtmp8jwsge'
dos2unix: problems converting file pesc.add

has anyone experienced same issue?
i'm using dos2unix 3.0 under SuSE.
please help.

I've sometimes had issues similar to that. I found life is a lot easier with dos2unix and unix2dos when both source and destination files are in your current working directory.

Thanks,
but same problem running dos2unix with source & dest in same working directory.

eg.
-------------------------------------
dos2unix myfile // or myfile myfile2
-------------------------------------

Is there any possible scratch in code level??? i remember there was kinda old thread regarding similar error in dos2unix.

thanks.

Using sed you could do:

Code:

#!/bin/bash
##
## ^M in next line is created by pressing Ctrl+v then Ctrl+m
sed 's/^M$//' $1 > $2

or directly from the command line:
sed 's/^M$//' origfile > newfile

I just learned something with that Ctl-v trick! Thanks

If you don't like dealing with the control characters and you simply want to strip out all carriage returns (whether or not they immediately precede a newline) you can also:

Code:

cat origfile | tr -d "\r" > newfile

As far as unix2dos/dos2unix are concerned, I just looked around at the versions I had and discovered those files on my Ubuntu system are actually symlinks to todos/fromdos, which appear to be by a different author (and lower revision numbers). So you could also check out that package (probably have to compile it yourself) and see if you have any better luck.

Description of problem:
The problem is in 'dos2unix-3.1-tmppath.patch'. Memory for the null
terminator is not being allocated.

this code:
fname_len = strlen(dir) + strlen("/d2utmpXXXXXX");

should be:
fname_len = strlen(dir) + strlen("/d2utmpXXXXXX") + sizeof(char);

Version-Release number of selected component (if applicable):
dos2unix-3.1-21

How reproducible:
Sometimes

Steps to Reproduce:
1. dos2unix ./source/common/launch.h

Actual Results: dos2unix: converting file ./source/common/launch.h to
UNIX format ...
dos2unix: problems renaming './source/common/d2utmptfS3dJ' to
'./source/common/launch.h'
output file remains in './source/common/d2utmptfS3dJ'
