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. Show Sample Output

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. Show Sample Output
This is sample output - yours may be different.

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.) Show Sample Output

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

Ensure path permissions from '.' prior to root

`pwd` returns the current path `grep -o` prints each slash on new line perl generates the paths sequence: './.', './../.', ... `readlink` canonicalizes paths (it makes the things more transparent) `xargs -tn1` applies chmod for each of them. Each command applied is getting printed to STDERR. Show Sample Output

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Recover remote tar backup with ssh

Here how to recover the remote backup over ssh

Reuse all parameter of the previous command line

!* is all of the arguments to the previous command rather than just the last one. This is useful in many situations. Here's a simple example: $ vi cd /stuff oops! [exit vi, twice] $ !* expands to: cd /stuff

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

recursive search and replace old with new string, inside files

recursively traverse the directory structure from . down, look for string "oldstring" in all files, and replace it with "newstring", wherever found also: $ grep -rl oldstring . |xargs perl -pi~ -e 's/oldstring/newstring'

Find the process you are looking for minus the grepped one

faster ;) but your idea is really cool

Compression formats Benchmark

See: http://imgur.com/JgjK2.png for example. Do some serious benchmarking from the commandline. This will write to a file with the time it took to compress n bytes to the file (increasing by 1). Run: $ gnuplot -persist

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Lists installed kernels

no need for rpm, no need for piping to another command. also no real fu but lacking in unnecessary complexity and distro specific commands.

Diff two directories by finding and comparing the md5 checksums of their contents.

Compares the md5 checksums of the contents of two directories, outputting the checksum and filename where any files differ. Shows only the file name, not the full path.

Create higher quality gif from videos

I had to compress it a bit to meet the 255 limit. See sample for full command (274) usage: ffgif foo.ext Supports 3 arguments (optional) ffgif filename seek_time time_duration scale ffgif foo 10 5 320 will seek 10 seconds in, convert for 5 seconds at a 320 scale. Default will convert whole video to gif at 320 scale. Inspiration - http://superuser.com/questions/556029/how-do-i-convert-a-video-to-gif-using-ffmpeg-with-reasonable-quality/556031#556031
