Full Discussion: Shell script process remains after "exit 1"
Top Forums Shell Programming and Scripting Shell script process remains after "exit 1" Post 302249462 by Squeakygoose on Tuesday 21st of October 2008 11:17:01 AM

Confirmed. feeding the pipe some dummy text (with an implicit EOF) before removing it causes the script to exit correctly:

Code:
cleanup()
{
if [ ${compress:-N} = Y ]
then
        echo "fail" >> ${pipe_name}
        rm -f ${pipe_name}
fi
}

Presumably the issue is coming from the gzip command not returning an exit code to the script process before it disappears, keeping the script process open. Killing the pipe before it feeds the gzip process anything seems to leave the script process in limbo. Feeding the dummy text is an OK workaround but it leaves me with the .gz file after a failure.

Does anyone know how to send JUST the EOF to a pipe? I'm hoping that this will cause the background gzip process to exit cleanly without creating a .gz file.

gzforce

GZFORCE(1)						      General Commands Manual							GZFORCE(1)

NAME

       gzforce - force a '.gz' extension on all gzip files

SYNOPSIS

       gzforce [ name ...  ]

DESCRIPTION

       gzforce	forces a .gz extension on all gzip files so that gzip will not compress them twice.  This can be useful for files with names trun-
       cated after a file transfer.  On systems with a 14 char limitation on file names, the original name is truncated to make room for  the  .gz
       suffix. For example, 12345678901234 is renamed to 12345678901.gz. A file name such as foo.tgz is left intact.

SEE ALSO

       gzip(1), gznew(1), gzmore(1), gzgrep(1), gzdiff(1), gzexe(1)
