Commands tagged cut

poor man's xml parser :)

Schematics:

command [options] [paste your variable here] parameter

command [options] [paste entire column of variables here] parameter

...

(hard-code command "c" and parameter "e" according to your wishes: in example shown command = "cp -a" and parameter = "~")

Features:

- Quick exchange only variable part of a long command line

- Make variable part to be an entire column of data (i.e. file list)

- Full control while processing every single item

Hints:

Paste column of data from anywhere. I.e. utilize the Block Select Mode to drag, select and copy columns (In KDE Konsole with Ctrl+Alt pressed, or only Ctrl pressed in GNOME Terminal respectively).

Disadvantages:

You can paste only one single variable in a row. If there are more space separated variables in a row only first one will be processed, but you can arrange your variables in a column instead. To transpose rows to columns or vice versa look at Linux manual pages for 'cut' and 'paste'.

TODO:

- add edit mode to vary command "c" and parameter "e" on the fly

- add one edit mode more to handle every list item different

- add y/n/a (=All) instead of only y(=default)/n to allowed answers

Disclaimer:

The code is not optimized, only the basic idea is presented here. It's up to you to shorten code or extend the functionality.

Enhancement for the 'busy' command originally posted by busybee : less chars, no escape issue, and most important it exclude small files ( opening a 5 lines file isn't that persuasive I think ;) )

This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim.

Saves one character, the original is probably clearer

You can also cut charactes starting from X to N.

In case sed and awk are not available you may use this to remove the last character from a string with "rev" and "cut".

Expand a URL, aka do a head request, and get the URL. Copy this value to clipboard.

Grabs the Apache config file (yielded from httpd) and returns the path specified as DocumentRoot.

Nothing special about hashing here, only the use of cut, I think, could result at fewer keystrokes.

list top committers (and number of their commits) of svn repository.

in this example it counts revisions of current directory.

This is what we use.

You can grep -v 127.0.0.1 if you wish.

Lightweight alternative with case

displays current time in "binary clock" format

(loosely) inspired by: http://www.thinkgeek.com/homeoffice/lights/59e0/

"Decoding":

8421

.... - 1st hour digit: 0

*..* - 2nd hour digit: 9 (8+1)

.*.. - 1st minutes digit: 4

*..* - 2nd minutes digit: 9 (8+1)

Prompt-command version:

PROMPT_COMMAND='echo "10 i 2 o $(date +"%H%M"|cut -b 1,2,3,4 --output-delimiter=" ") f"|dc|tac|xargs printf "%04d\n"|tr "01" ".*"'

this will dump a list of domains one per line into a text file

Here's an awk alternative, for those lacking the version of cut with the --complement argument.

Show all columns except 5th. This might help you save some typing if you are trying to exclude some columns from the output.

Use this BASH trick to create a variable containing the TAB character and pass it as the argument to sort, join, cut and other commands which don't understand the \t notation.

Most systems (at least my macbook) have system users defined, such as _www and using "users" for example will not list them. This command allows you to see who the 'virtual' users are on your system.
