I have no idea where the problem is, but I got one ME TOO which confirmed that not only I have the problem with tar saying: "Child died with signal 13". So, Windows 2000, Windows 2000 Server and Windows NT4 SP6 have the problem, Windows 98 and any other *nix machine I testet have not. I think it's cygwin related! Because I have no idea where to look in the cygwin sources I decided the only way to help the developers *YOU* is to build a more simple testcase. Here it comes: -------------------------- Administrator@LISI ~/qqq $ tar -czvf a.tar.gz a/ a/ a/error.txt Administrator@LISI ~/qqq $ tar -tzvf a.tar.gz drwxrwxrwx Administratoren/Kein 0 2002-03-01 14:22:18 a/ -rwxrwxrwx Administratoren/Kein 8193 2002-03-01 14:21:15 a/error.txt tar: Child died with signal 13 tar: Error exit delayed from previous errors Administrator@LISI ~/qqq $ tar -cvf a.tar a/ a/ a/error.txt Administrator@LISI ~/qqq $ ll total 21 drwxrwxrwx 2 Administ Kein 0 Mar 1 14:22 a -rw-rw-rw- 1 Administ Kein 20480 Mar 1 14:26 a.tar -rw-rw-rw- 1 Administ Kein 299 Mar 1 14:23 a.tar.gz -------------------------- You can get a.tar.gz at: http://www.scytek.de/a.tar.gz . The problem is related to the length of the tar file. If you delete one charakter in error.txt, and its length drops to 8192 then the length of the tar file drops to 10240 bytes and you don't get the "tar: Child died with signal 13". I didn't test how many bytes one has to add to let the error vanish. Hope this makes it easy to find the problem.
