This is a bundle of scripts that I usually install in every linux machine I need to work. It makes a few personal tweaks in environment configuration, described below. Useful also when using third servers (as website hostings), where I use to have control only over my home folder.

Install

For a single account (no root privilege needed)

cd ~
git clone https://github.com/paulera/files
cp ~/.bashrc ~/.bashrc.old
echo "if [ -f ~/files/bash.d/run_bash ]; then . ~/files/bash.d/run_bash; fi" >> ~/.bashrc

For all users (suggestion: inside /opt folder)

cd /opt
sudo git clone https://github.com/paulera/files

# This command adds the run_bash call in each EXISTING user's .bashrc file. Change "USER" for the username
cp /home/USER/.bashrc /home/user/.bashrc.old # backup
echo "if [ -f /opt/files/bash.d/run_bash ]; then . /opt/files/bash.d/run_bash; fi" >> /home/USER/.bashrc

# This command adds the run_bash call to root's .bashrc file
sudo cp /root/.bashrc /root/.bashrc.old # backup
echo "if [ -f /opt/files/bash.d/run_bash ]; then . /opt/files/bash.d/run_bash; fi" >> /root/.bashrc

# This command makes the run_bash call available for NEW users
sudo cp /etc/skel/.bashrc /etc/skel/.bashrc.old # backup
echo "if [ -f /opt/files/bash.d/run_bash ]; then . /opt/files/bash.d/run_bash; fi" >> /etc/skel/.bashrc

Note that these commands will:

• create a folder files
• make a backup of your bashrc file with .old extension
• append to your bashrc file a command that runs files/bash.d/run_bash

Features

INSTALL STANDALONE APPLICATIONS

The $FILESROOT/soft_installers folder, there are 2 kind of files:

• installer_base.sh: Every installer use this file, calling it with dot (so its contents will be 'injected' on the installer) and then calling the installer_bootstrap function. After that, the installer can use the $APPFOLDER variable to do the installation. See examples.
• other installers: the others files inside the soft_installers folder are intented to install those application inside $FILESROOT/soft. The reason for that is to shrink the bundle size, make it fexible and also easy to upgrade.

SPECIAL FOLDERS

If a user create these directories inside home, they will have the described behavior:

• ~/bash.d: all .sh files inside this directory will be executed everytime you open a terminal or do an ssh.
• ~/bin: folder to store custom scripts, referenced in PATH environment variable. The scriptme command use this folder.
• ~/soft: just a folder intented to centralize standalone software. It's recommended to have their executables linked at bin folder

Note that the $FILESROOT folder also have these subfolders, and the mentioned behaviors will be applied to both.

ENVIRONMENT

• Create a $FILESROOT environment var, pointing to the files location
• Apply more specific colors to dirs using the file $FILESROOT/dircolors
• Change the PS1 format
• see $FILESROOT/bash.d/02_alias.sh for more

TWEAKS

• Turns bash autocompletion case INsensitive

FUNCTIONS

• extract <file>: identify the file type by extension and try to extract
• ff "Text to find": search for the text inside all files (using grep). -R to do it recursively.

SHELL SHORTCUTS

All shell shortcuts are defined in files/bash.d/04_shell_sortcuts.sh

• files: go to '$FILESROOT' folder
• down: go to ~/downloads
• desk: go to ~/desktop
• img: go to ~/images
• doc: go to ~/documents
• mp3: go to ~/mp3

Smart shortcuts

• soft: go to the soft folder
• bashd: go to bash.d folder
• bin: go to bin folder

A smart shortcut first looks for the folder inside home folder. If the user have not created such directory, you will be redirected to the directories inside $FILESROOT location. To force smart shortcuts to take you to the respective $FILESROOT subdirectory, use 2 as parameter: bin 2, for example

SCRIPTS inside files/bin

• dirsize: list the size of everything, in the current dir
• doloop : Execute the command, repeatedly, with 1 second pause, clearing screen. Some bugs when using piped commands.
• externalip: return the IP address seen by the web
• localip: return the local network IP address
• now: current time in HH:MM:SS (24h format)
• psaux : do the ps aux, grepping the parameter - ex: psaux java
• remove_cr: Fix all lines in a file (or all files in current folder) to make them end with just LF, removing all CR characters.
• scriptme: one of my favourites. Create a script inside ~/bin and edits it in vim. It will start with the $FILESROOT/script_template contents, and will have *chmod +x if you leave vim saving it.
• today: current date as YYYY-MM-DD
• trash: send files to ~/.trash
• unmd5: Uses Insomnia247.nl Hashdb API to lookup a MD5 hash
• unsha1: Uses Insomnia247.nl Hashdb API to lookup a SHA1 hash

TO-DO list:

• Document set_defaults folder
• Document the soft installers
