So, what is it exactly in the records (and/or values given to subprogram.sh) where the execution stops? - Parv -- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

shell scripting: help appreciated
short and weird problem description (from my point of view): /bin/sh stops working correctly with a content-controlled do-loop. the shell-script layout is as follows: (it's not that trivial, just to show the meaning) --- /test/foo.conf (originally ~60 lines): test1 testval1optional_testval1 test2 testval2optional_testval2 /test/foo.sh (this is the original loop code): cat "$g_dir_etc/compile.lst"|\ sed -e 's-^ *--g'|\ sed -e 's-^ *--g'|\ grep -v '^#'|\ sed -e 's-#.*$--g'|\ grep -v '^$'|\ while read gh_name gh_src gh_srcdir do /bin/sh -c subprogram.sh $h_val1 $h_val2 $h_opt1; done; /test/foo_sub.sh: --- if i change the line /bin/sh -c subprogram.sh $h_val1 $h_val2 $h_opt1; to echo /bin/sh -c subprogram.sh $h_val1 $h_val2 $h_opt1; the program loops for all records in the foo.conf correctly. if i remove the "echo" keyword, the sub-script get's executed, but the shell terminates as if there were lesser records in the foo.conf file! i scripted as many debug messages as possible, for every loop they get executed and there are no errors/etc... happening. and interestingly, the execution stops always on the same record! if i comment out some records of my foo.conf, the sub-shell gets executed for more records. it seems like something with a buffer or somewhat, but i'm not a debugger/c-guru, so i don't know where to start here... maybe i'm using a wrong technique for looping? some facts: conf-file is readable and doesn't change during execution the scripts also don't change during exec we're running on 6.1-RELEASE with 2GB RAM and a XEON 2.8 no errors/warnings during exec-time from kernel or daemons fs is fine, fsck is happy! everything runs /bin/sh. the whole scripts runs currently ~45min. if i change the subshell to an empty script with just "hi i'm here" and "exit 1;" the loop works for all records in the .conf file. any ideas, what the hell is going on here? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
