SVN Status log to CSV (Mac OSX friendly)

This is a minor variation to cowboy's submission - his script worked great on Ubuntu, but the sed gave issues on osx (which used BSD). Minor tweaks (sed -E instead of sed -r and \'$'\n to handle the new line made it work.

Clean a wordlist for use with password cracking tools and rules

Using large wordlists is cumbersome. Using password cracking programs with rules such as Hashcat or John the ripper is much more effective. In order to do this many times we need to "clean" a wordlist removing all numbers, special characters, spaces, whitespace and other garbage. This command will covert a entire wordlist to all lowercase with no garbage.

Print all words in a file sorted by length

Take a file and ,."()?!;: give a list of all the words in order of increasing length. First of all use tr to map all alphabetic characters to lower case and also strip out any puntuation. A-Z become a-z ,."()?!;: all become \n (newline) I've ignored - (hyphen) and ' (apostrophe) because they occur in words. Next use bash to print the length ${#w} and the word Finally sort the list numerically (sort -n) and remove any duplicates (sort -u). Note: sort -nu performs strangely on this list. It outputs one word per length. Show Sample Output

hostgrep: set ip and hostname from /etc/hosts (non-DNS)

usage: dng BRE [selection] default selection is the last match DNS is ok, but although domainnames may be easier to remember than IP numbers, it still requires typing them out. This can be error-prone. Even more so than typing IPv4 numbers, depending on the domainname, its length and complexity.

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Convert any sequence of spaces/tabs to single space/tab

Remove empty lines additionally: $ tr -s ' \t\n' 2.txt identical with: $ tr -s '[:space:]' 2.txt To "clean perfectly" a text or code file, You can combine this command with another one: $ while read l; do echo -e "$l"; done 2.txt (= remove all leading and trailing spaces or tabs from all lines of a text file)

Convert mysql database from latin1 to utf8

MySQL: CHARSET from latin1 to utf8

Shows picture exif GPS info if any and converts coords to a decimal degree number

This oneliner uses Imagemagic's identify utility to show the exif GPS information of an image an also converts Grad/MIn/Sec representation to a decimal degree number

Quicker move to parent directory

Alias two dots to move to parent directory. Put it into your .bashrc or .profile file.

Rename all images in current directory to filename based on year, month, day and time based on exif information

Get list of servers with a specific port open

Change the -p argument for the port number. See "man nmap" for different ways to specify address ranges.

shell function to underline a given string.

underline() will print $1, followed by a series of '=' characters the width of $1. An optional second argument can be used to replace '=' with a given character. This function is useful for breaking lots of data emitted in a for loop into sections which are easier to parse visually. Let's say that 'xxxx' is a very common pattern occurring in a group of CSV files. You could run $ grep xxxx *.csv This would print the name of each csv file before each matching line, but the output would be hard to parse visually. $ for i in *.csv; do printf "\n"; underline $i; grep "xxxx" $i; done Will break the output into sections separated by the name of the file, underlined.

Ctrl+S Ctrl+Q terminal output lock and unlock

These are simple shortcuts to pause and continue terminal output, works in most terminals and screen multiplexers like screen. You can use it to catch something if things change too fast, and scroll with Shift + PgUp PgDown. On linux console ScrollLock can also be used.

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"
