Commands tagged cut

Most systems (at least my macbook) have system users defined, such as _www and using "users" for example will not list them. This command allows you to see who the 'virtual' users are on your system.

I've been using it in a script to build from scratch proxy servers.

The ^python$ is a package name patten. You can change whatever you want.

The cut should match the relevant timestamp part of the logfile, the uniq will count the number of occurrences during this time interval.

Change the cut range for hits per 10 sec, minute and so on... Grep can be used to filter on url or source IP.

A command to find out what the day ends in. Can be edited slightly to find out what "any" output ends in.

NB: I haven't tested with weird and wonderful output.

This version makes uses of Bash shell expansion, so it might not work in all other shells.

grabs your local IP Address.

as unixmonkey7109 pointed out, first awk parse replaces three steps.

It's not a big line, and it *may not* work for everybody, I guess it depends on the detail of access_log configuration in your httpd.conf. I use it as a prerotate command for logrotate in httpd section so it executes before access_log rotation, everyday at midnight.

Sometimes, you don't really care about all the other information that ifconfig spits at you (however useful it may otherwise be). You just want an IP. This strips out all the crap and gives you exactly what you want.

miss a class at UTOSC2010? need a refresher? use this to curl down all the presentations from the UTOSC website. (http://2010.utosc.com) NOTE/WARNING this will dump them in the current directory and there are around 37 and some are big - tested on OSX10.6.1

I never can remember the syntax of awk. You can give a different -d option to cut to separate by e.g. commas. Also this allows to do more things with the generated SQL, e.g. to redirect it into different files.

Based on the MrMerry one, just add some visuals to differentiate files and directories

"cut" the user names from /etc/passwd and then running a loop over them.

This one will work a little better, the regular expressions it is not 100% accurate for XML parsing but it will suffice any XML valid document for sure.

grep -o puts each occurrence in a separate line

grep's -c outputs how may matches there are for a given file as "file:N", cut takes the N's and awk does the sum.

This set of commands was very convenient for me when I was preparing some xml files for typesetting a book. I wanted to check what styles I had to prepare but coudn't remember all tags that I used. This one saved me from error-prone browsing of all my files. It should be also useful if one tries to process xml files with xsl, when using own xml application.
