change the path where you are, when is executed, is usefule when you've got folders to classify something like a tags, you've got devel/dist, android/ios, etc. like:

~user/Documents/devel/project

~user/Documents/dist/project

You can change between devel/project folder to dist/project without leave project.

If somebody has a better idea to do that without replace command.

Change current working directory with root permissions.

Place this snippet in your .bashrc to add a new "sudocd" command:

function sudocd { sudo bash -c "cd $1;bash" }

Usage: sudocd DIRECTORY

Please note that if you will use this command to cd into directories with the permissions allowing only root to be in them, you will have to use sudo as a prefix to every command that changes/does something in that directory (yes, even ls).

for a in $(seq 15); do (xset led 3);(xset -led 3);sleep .9;done

If the password for the share your trying to mount contains special characters you can use URL escape characters.

The above command uses an example as follows:

username: user

password: p@ss

URL Encoded password: p%40ss

# AllInOne: Update what packages are available, upgrade to new versions, remove unneeded packages

# (some are no longer needed, replaced by the ones from ap upgrade), check for dependencies

# and clean local cached packages (saved on disk but not installed?,some are needed? [this only cleans unneeded unlike ap clean]).

# aliases (copy into ~/.bashrc file):

alias a='alias'

a ap='apt-get'

a r='ap autoremove -y'

a up='ap update'

a u='up && ap upgrade -y --show-progress && r && ap check && ap autoclean'

# && means "and run if the previous succeeded", you can change it to ; to "run even if previous failed".

I'm not sure if ap check should be before or after ap upgrade -y, you can also change the alias names.

# To expand aliases in bash use ctrl alt e or see this ow.ly/zBKHs

# For more useful aliases go to ow.ly/zBMOx

jrk's aria2 example is incorrect. -s specifies the global connection limit; the per-host connection limit is specified with -x.
