  • # 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

Display laptop battery information

Takes and displays screenshot of Android phone over adb.
Dependencies on phone: adb access, screencap command, base64 command. Dependencies on computer: adb, sed, base64, display (from imagemagick, but can substitute other image viewer which reads from stdin). This should work around adb stupidies (i.e. that it replaces \n with \r\n) with base64.

count and number lines of output, useful for counting number of matches
Write each FILE to standard output, with line numbers added. With no FILE, or when FILE is -, read standard input.

check open ports without netstat or lsof

fast access to any of your favorite directory.
example: -------------------------------------------------------------------------------------------- user@ubuntu:~/workspace/SVN/haystak-repos/trunk/internal/src$ addpi -------------------------------------------------------------------------------------------- Now that directory is in the list of fast access directories. You can switch to it anytime like this: -------------------------------------------------------------------------------------------- user@ubuntu:~$ pi internal` user@ubuntu:~/workspace/SVN/haystak-repos/trunk/internal/src$ -------------------------------------------------------------------------------------------- Please note the backquote ( the symbol that shares its key with ~ in the keyboard ) pi will switch you to that directory. To see the list of all fast access directories you have to say "cat ~/.pi"

Compare two CSV files, discarding any repeated lines
The value for the sort command's -k argument is the column in the CSV file to sort on. In this example, it sorts on the second column. You must use some form of the sort command in order for uniq to work properly.

show the date every rpm was installed
the newest rpms are at the top; individual packages can also be queried this way: rpm --last -q package
