Find files modified in the last 5 days, no more than 2 levels deep in the current directory.

Ever wanted to find the most recently modified files, but couldn't remember exactly where they were in a project directory with many subdirectories? The "find" command, using a combination of "-mtime -N" and "-depth -D" can be used to find those files. If your directory structure isn't very deep, just omit the "-depth -D", but if your directory structure is very deep, then you can limit the depth of the traversal using "-depth -D", where "D" is the maximum number of directory levels to descend.

do a directory disk usage summary without giving the details for the subdirectories

Sometimes you want to know the summary of the sizes of directories without seeing the details in their subdirectories. Especially if it is going to just scroll off the screen. This one liner summarizes the disk usage of any number of directories in a directory without giving all the details of whats happening underneath. Show Sample Output

```
dir1 500

Get your external IP address without curl

Curl is not installed by default on many common distros anymore. wget always is :) $ wget -qO- ifconfig.me/ip

grep binary (hexadecimal) patterns

-P activates the Perl regular expression mode.

Use a var with more text only if it exists

See "Parameter Expansion" in the bash manpage. They refer to this as "Use Alternate Value", but we're including the var in the at alternative.

Tar files matching a certain wildcard

This is a shortcut to tar up all files matching a wildcard. Tar doesn't have the --include (apparently).

Scan a document to PDF

Adjust the --resolution and --mode as required (if these options are available for your scanner). The size options (-x, -y, -imageheight, -imagewidth) are for US letter paper. For A4, I think the command would be: $scanimage -p --resolution 250 --mode Gray -x 210 -y 297 | pnmtops -imageheight 11.7 -imagewidth 8.3 | ps2pdf - output.pdf

check open ports without netstat or lsof

convert markdown to PDF

This is the one-line version of this htmldoc + markdown combo to convert markdown formatted text to PDF files to distribute to your non-savvy project managers. http://scottnesbitt.net/ubuntublog/?p=114

execute command on all files of certain types excluding folders that match pattern

Display Spinner while waiting for some process to finish

alternatively, run the spinner for 5 seconds: timeout 5 bash -c 'spinner=( Ooooo oOooo ooOoo oooOo ooooO oooOo ooOoo oOooo); while true; do for i in ${spinner[@]}; do for j in seq 0 ${#i}; do echo -en "\b\b"; done; echo -ne "${i}"; sleep 0.2; done; done'

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"
