Why?
Could somebody explain and help me to make it work.
Thanks
Is there a way to collect data from top command to a file at regular intervals. I need this on HP-UX. I need to gather resident memory usage. I know that sar will give %cpu usage. There is a pmap command which gives memory usage in solaris. Is there a similar command in HP-UX

I have to confirm that an engine was not able to run. In the output below you see that it indeed got errors, but it didn't send those messages to the output file.

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
