git log --format=%H | tail -1 doesn't work anymore

This is similar to using `!!` or

In bash 4.1 it seems you can bind directly to a shell command, but I'm not running that version.

This article will relate to self-study with three kinds of PDF software: PDF Editor, PDF converter and PDF password recovery software. Afterwards, you will never worry about handling PDF files.

find . -type f -iname '*.flac' # searches from the current folder recursively for .flac audio files

| # the output (a .flac audio files with relative path from ./ ) is piped to

while read FILE; do FILENAME="${FILE%.*}"; flac -cd "$FILE" | lame -b 192 - "${FILENAME}.mp3"; done

# for each line on the list:

# FILE gets the file with .flac extension and relative path

# FILENAME gets FILE without the .flac extension

# run flac for that FILE with output piped to lame conversion to mp3 using 192Kb bitrate

Like the http://www.commandlinefu.com/commands/view/6327/open-file-with-sudo-when-there-is-no-write-permission, but works (in zsh; my commandlinefu is not strong enough to understand why bash don't like it) with vim options, like -O, and many input files.

There could be other mistakes.

If you would like to ignore a directory including its subdirectory. For example, a tmp/ directory

cmd? is the prompt.

instmodsh is a perl script. To view it use your fav editor. i.e.

vi $(which instmodsh)

Tee can be used to split a pipe into multiple streams for one or more process to work it. You can add more " >()" for even more fun.

When working on a big proeject with SVN, you create quite much files, for now! Can just sit here and type svn add for all of them!

svn status will return a list of all of file which get ?(not add), "M"(Modified), "D"(Deleted)! This code just grep "?" flag, then add it into SVN again!

This works in bash. The "!!:0" limits the argument to man to be only the first word of the last command. "!!:1" would be the second, etc.

Prepends all directory items with "prependtext"

all files in the directory get moved, in doing so the new name of the file is the original name with out spaces (using translate command)

this avoids several VIM warnings, which I seem too stupid to disable: warning, readonly! and: file and buffer have changed, reload?!

If you want a sequence that can be plotted, do:

seq 8 | awk '{print "e(" $0 ")" }' | bc -l | awk '{print NR " " $0}'

Other bc functions include s (sine), c (cosine), l (log) and j (bessel). See the man page for details.

Test whether real-time virus detection is working by running this command and checking for eicar.com in /tmp. Requires real-time scanning to be enabled and active on the /tmp directory. If scanning is active, the file should be quarantined/deleted (depending on your settings) moments after running this command. If not, the (harmless) test file should remain in your /tmp directory.

I have a mac, and do not want to install mac ports to get the base64 binary. Using openssl will do the trick just fine. Note, to decode base64, specify a '-d' after 'base64' in the command. Note also the files base64.decoded.txt and base64.encoded.txt are text files.

All with only one pipe. Should be much faster as well (sort is slow). Use find instead of ls for recursion or reliability.

Edit: case insensitive

Gets you the latest of everything, and removes any remaining junk. The "sh -c" part is so that you'll only run a single sh command, so you won't get asked more than once for the password.

Splitting on tags in awk is a handy way to parse html.
