This file provides a couple of useful examples of recs chains and how each of them break down. This is meant as a learning tool for folks new recs that would like to see some cool things you can do with RecordStream. Another good resource is 'man recs-story' which is a humorous story meant to get the newest users used to recs.
How many processes are each of the users on my system running?
recs-fromps | recs-collate --key uid -a count | recs-sort --key count=n | recs-totable Broken down this is: 1. recs-fromps - First get the records of all the prcesses currently running 2. recs-collate --key uid -a count Grouping by the uid field, count how many records fall into the group 3. recs-sort --key count=n Sort the resulting records by the count key numerical (rather than lexically) 4. recs-totable - Print the output in a nicely formatted table.
How many processes are each user on the system running at each priority level?
recs-fromps | recs-collate --key uid,priority -a count | recs-toptable --x priority --y uid --v count Broken down: 1. recs-fromps - First get the records of all the prcesses currently running 2. recs-collate --key uid,priority -a count Grouping by the uid and the priority field, count how many records fall into the group 3. recs-toptable --x priority --y uid -v count Create a 2 dimensional table, across the top put the priority values, down the side put the uid. In put the value of the count field in the cell
What Xorg modules put information in my Xorg.log at startup, and what log level are they logged at? I need this in csv format for importing into a spreadsheet program.
recs-frommultire --re 'type,module=\((\S*)\) ([^:]+):' /var/log/Xorg.0.log | recs-collate --key type,module -a ct | recs-sort --key ct=n | recs-tocsv --header 1. recs-frommultire --re 'type,module=\((\S*)\) ([^:]+):' /var/log/Xorg.0.log Parse out the type and module from the Xorg log file. That regex reads capture text inside literal '()', then capture text after a space up to the first ':'. 2. recs-collate --key type,module -a ct Collate records into groups of type-modules. Count how many in each group across all records. 3. recs-sort --key ct=n Sort by the count, numerically. 4. recs-totable --spreadsheet --delim ',' Output a table in spreadsheet format (no ASCII art), delimited by commas instead of tabs
