Top Forums UNIX for Dummies Questions & Answers Please explain this grep command Post 302797329 by alister on Monday 22nd of April 2013 11:04:58 AM

Looks like a hack to print all lines after and including the first to match 'server.log' and then count those with Option=[Yes]. It assumes that the number of lines left in the file will be less than or equal to 999999.

I don't see the point of it. The following does the same job without the line count limitation:
Code:
sed -n '/server\.log/,$ { /Option=\[Yes]/p; }' | wc -l

Note that the 'server.log' in that grep command is almost certainly incorrect. The dot is behaving as a wildcard when what's most likely intended is a literal dot.

Regards,
Alister

NAME
pqstat - List jobs in NetWare print queue SYNOPSIS
pqstat [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -B ] queue name [ job count ] DESCRIPTION
pqstat lists specified number of jobs from the specified NetWare print queue available to you on some server. If you are already connected to some server, this one is used. If pqstat does not print to a tty, the decorative header line is not printed, so that you can count the jobs in print queue by doing pqstat -S server queue | wc -l pqstat looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information. Please note that the access permissions of .nwclient MUST be 600, for security reasons. OPTIONS
queue name queue name is used to specify queue. You can not use wildcards in the name. job count job count is used to specify how much entries will be shown. Default is to show all entries. -S server server is the name of the server you want to use. -U user name If the user name your NetWare administrator gave to you differs from your unix user-id, you should use -U to tell the server about your NetWare user name. -P password You may want to give the password required by the server on the command line. You should be careful about using passwords in scripts. -n -n should be given to mount shares which do not require a password to log in. If neither -n nor -P are given, pqstat prompts for a password. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. -B By default, pqstat lists the Netware name of the print job owner. -B causes it to list the banner name instead. SEE ALSO
