Commands tagged output redirection (3)

  • Loops over files, runs a command, dumps output to a file

    In this case I'm selecting all php files in a dir, then echoing the filename and piping it to ~/temp/errors.txt. Then I'm running my alias for PHPCS (WordPress flags in my alias), then piping the PHPCS output to grep and looking for GET. Then I'm piping that output to the same file as above. This gets a list of files and under each file the GET security errors for that file. Extrapolate this to run any command on any list of files and pipe the output to a file. Remove the >> ~/temp/errors.txt to get output to the screen rather than to a file. Show Sample Output


    1
    for f in *php; do echo $f >> ~/temp/errors.txt; phpcsw $f | grep GET >> ~/temp/errors.txt; done

Get the Volume labels all bitlocker volumes had before being encrypted
Get information of volume labels of bitlocker volumes, even if they are encrypted and locked (no access to filesystem, no password provided). Note that the volume labels can have spaces, but only if you name then before encryption. Renaming a bitlocker partition after being encrypted does not have the same effect as doing it before.

Countdown Clock
The biggest advantage over atoponce's nifty original is not killing the scrollback. Written assuming bash, but shouldn't be terribly difficult to port to other shells. S should be multiple spaces, but I can't get commandlinefu to save/show them properly, any help?

Debug a remote php application (behind firewall) using ssh tunnel for XDEBUG port 9000
If you need to xdebug a remote php application, which is behind a firewall, and you have an ssh daemon running on that machine. you can redirect port 9000 on that machine over to your local machine from which you run your xdebug client (I am using phpStorm) So, run this command on your local machine and start your local xdebug client, to start debugging. more info: http://code.google.com/p/spectator/wiki/Installing

Advanced python tracing
Trace python statement execution and syscalls invoked during that simultaneously

erase content from a cdrw

uniq without pre-sorting
Reads stdin, and outputs each line only once - without sorting ahead of time. This does use more memory than your system's sort utility.

Show a git log with offsets relative to HEAD
Print a git log (in reverse order) giving a reference relative to HEAD. HEAD (the current revision) can also be referred to as HEAD~0 The previous revision is HEAD~1 then HEAD~2 etc. . Add line numbers to the git output, starting at zero: $ ... | nl -v0 | ... . Insert the string 'HEAD~' before the number using sed: $ ... | sed 's/^ \+/&HEAD~/' . Thanks to bartonski for the idea :-)

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"

Quick searching with less
This command enables the user to append a search pattern on the command line when using less as the PAGER. This is especially convenient (as the example shows) in compressed files and when searching man pages (substituting the zcat command with man, however).
