Fred,
Ignore those errors. They're a result of a race condition between "tar" and
the "gunzip" sub-process forked to handle the compressed archive and the
fact that there's some ignored trailing byes in the uncompressed data
stream coming from gunzip. The "-B" flag to tar might suppress this message.
The way I search the User Guide or API document is by using "egrep -l" on
the HTML files then opening the files with hits in my browser. I do it so
infrequently I have not tried to script it, but it would not be difficult.

Just a follow-up to the attached with further details. Contrary to what I
said, rebooting doesn't help (though it did at one point). Other odd
behaviour is that "gunzip --help" and "gzip --help" seem to send the help
information all over the screen, as if there were weird tabs randomly
thrown. Strangely, the help info looks OK if I pipe it through
"less". Also, "tar --help" does not give this crazy formatting.
I hope I don't have to upgrade cygwin. Now's not the greatest time....

Hello,
I'm using cygwin on WinME, installed Nov 11/2001, or such is the timestamp
on /setup.log. In that file, I have thelines
Starting cygwin install, version 2.78.2.15
and
Installing...latest/cygwin/cygwin-1.3.4-4.tar.bz2
I'm hoping I can solve the problem without upating my cygwin at the
moment, as it's not the greatest time right now.
The problem is when I use tar:
tar cvhzf safe/Paper.33.tgz `tar tzf safe/Paper.32.tgz`
I'm getting the file names from Paper.32.tgz and archiving all those files
to Paper.33.tgz.
It works usually. Sometimes, I get the error
tar: Child died with signal 13
tar: Error exit delayed from previous errors
But after these errors, the archive gets created anyway. Once these
errors start, they don't go away no matter how many times I issue the
command, regardless of whether I start up another cygwin window. From
brief experiment, it seems to go away if I reboot the computer.
I also get the errors if I simply try
tar tzf safe/Paper.22.tgz | cat
but not if I leave out the redirection to cat.
I've tried the mailing list search, but the engine died during one of the
refinements.
Thanks for any suggestions.
Fred
P.S. Is there a way to search the User Manual?
