Merge PDFs with Ghostscript wrapped in a function

This is an expansion on a previous entry, which I've wrapped in a function and placed in my profile. The "$@" is a positional parameter, much like "$*", but the parameters are passed on intact, without interpretation or expansion; so you can simply call the function like this: mergepdf * This will output a merged PDF of all PDFs in the current directory. Alternatively, you can simply list them like so: mergepdf 00.pdf 01.pdf 02.pdf ... N.B. Passing a wildcard will merge all PDFs in the current directory in name order, e.g. 00.pdf 01.pdf aa.pdf ab.pdf
This is sample output - yours may be different.

mergepdf() { gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=merged.pdf "$@" }

Check These Out

Set a Reminder for yourself via the notification system

This will be seen through your system's visual notification system, notify-osd, notification-daemon, etc. --- sleep accepts s,m,h,d and floats (date; sleep .25m; date) --- notify-send (-t is in milliseconds && -u low / normal / critical) man notify-send for more information --- notification-daemon can use b/i/u/a HTML

Sort files in folders alphabetically

Creates one letter folders in the current directory and moves files with corresponding initial in the folder.

Merge *.pdf files

Merge all pdf files in the directory into one pdf file (the out.pdf file)

Redefine the cd command's behavior

Often, the very next command after the cd command is 'ls', so why not combine them?. Tested on a Red Hat derivative and Mac OS X Leopard Update: changed ${1:-$HOME} to "${@:-$HOME}" to accomodate directories with spaces in the names

Turns red the stderr output

Netcat Relay

This is an example of using 3 hosts, in a netcat relay. first host connects to middle host 1 -> 2 Second hosts redirects to target host 1 -> 2 -> 3 I hope this makes sense.

No curl and no sed, just wget :)

Find the package that installed a command

Get MD5 checksum from a pipe stream and do not alter it

Identify all amazon cloudformation scripts recursively using ripgrep

This assumes you are in the cwd of where you put your s3 scripts. Its useful if someone decides to create aws cloudformation scripts and doesn't add the 'yaml' or .yml extension.
