If a directory contains softlinks, grep will give lot of warnings. So better use it along with find command so that softlinks are excluded. "Hn" operator will take care that both line number and filename is shown in grep output

Show git branches by date - useful for showing active branches

Add this line to your ~/.gitconfig for a git alias "git brd" (i.e., brd = (br)anch+(d)ate) which sorts branches by date. Allows you to pass in limited "git branch" options such as "-r" (remote) or "-a" (all). (Note: forum added "$" prefix to command; obviously in gitconfig there is no "$" prefix.)

Escape literal string for inclusion in an egrep regex

Use if you want to include untrusted literal strings in your grep regexes.

I use it to list all mounts below a directory:

dir=/mnt/gentoo; cat /proc/mounts |awk '{print $2}' |egrep "^$(egrep_escape "$dir")(/|$)"

/mnt/gentoo

/mnt/gentoo/proc

/mnt/gentoo/sys

/mnt/gentoo/dev

/mnt/gentoo/home

Works even if $dir contains dangerous characters (e.g. comes from a commandline argument).

sum and average of requests responses times or sizes in Apache2 access log

Depending on your Apache access log configuration you may have to change the sum+=$11 to previous or next awk token.

Beware, usually in access log last token is time of response in microseconds, penultimate token is size of response in bytes. You may use this command line to calculate sum and average of responses sizes.

You can also refine the egrep regexp to match specific HTTP requests.

Get the date for the last Saturday of a given month

This is a little trickier than finding the last Sunday, because you know the last Sunday is in the first position of the last line. The trick is to use the NF less than or equal to 7 so it picks up all the lines then grep out any empty lines.

Listing all your bundles Entities files to issue a doctrine:generate:entities

When I do a major change in my entities, I want to find a way to find all my Entities names and create the commande for me.

So instead of doing ls src/Your/OwnBundle... and then do it manually, this helps a lot.
