A small collection of some of the scripts I use frequently, kept here for easier distribution among the servers we work with. I usually clone this repo somewhere in home and then symlink the scripts I need to /usr/local/sbin.
Search files in current folder including ALL given words.
USAGE: andsearch "MATCH" [word1] [word2] ...
EXAMPLE: andsearch "*.txt" foo bar
Source: andsearch

A script for inserting a filament change at a certain height in a G-code file for Prusa-style 3D printers. Tested with Prusa MK2S, but should work with all printers that support the M600 g-code.
USAGE: color_change.py [change height mm] [path to gcode]

A Git script for doing a quick push-pull operation from a devel repository to a production repoistory. Both repositories must be in the same rootpath on the same webserver. Saves you the trouble of doing 'git push [wait], cd ../website, git pull [wait], cd ../website_devel. Includes basic checking for correct path and branch, dirty-state and unpushed commits.
Source: pushpull
A cron-schedulable script for uploading files using sftp. This script is only relevant if you don't have ssh shell access (server goes "This service allows sftp connections only"), otherwise, forget this convoluted hack and use scp or rsync instead.
Usage:
- A single file: sftp_put /payload/dir/file.txt [email protected] remote_directory
- Multiple files using an extension wildcard: sftp_put "/payload/dir/*.txt" [email protected] remote_directory
Note:
- Wildcard paths must be quoted
- Only *.[extension] wildcards are supported (
*,*.*orfile*won't work)
Credits: Thanks for the idea, Eric_G! (http://www.unix.com/unix-for-dummies-questions-and-answers/24994-sftp-batch-script.html)
