Commands tagged test

Pre-packaged python script that comes with Debian/Ubuntu.

Uses zsh globbing syntax to safely remove all the files known to be generated by LaTeX, but only if there is actually a .tex source file with the same basename present. So we don't accidentally delete a .nav .log or .out file that has nothing to do with LaTeX, e/'[[ -f ${REPLY:r}.tex ]]'/ actually checks for the existance of a .tex file of the same name, beforehand.

A different way to do this, would be to glob all *.tex files and generate a globbing pattern from them:

or, you could use purge() from grml-etc-core ( http://github.com/grml/grml-etc-core/blob/master/usr_share_grml/zsh/functions/purge )

Applies each file operator using the built-in test.

/home/askapache/.sq

-a True - file exists.

-d True - file is a directory.

-e True - file exists.

-r True - file is readable by you.

-s True - file exists and is not empty.

-w True - the file is writable by you.

-x True - the file is executable by you.

-O True - the file is effectively owned by you.

-G True - the file is effectively owned by your group.

-N True - the file has been modified since it was last read.

Full Function:

testt ()

{

local dp;

until [ -z "${1:-}" ]; do

dp="$1";

[[ ! -a "$1" ]] && dp="$PWD/$dp";

command ls -w $((${COLUMNS:-80}-20)) -lA --color=tty -d "$dp";

[[ -d "$dp" ]] && find "$dp" -mount -depth -wholename "$dp" -printf '%.5m %10M %#15s %#9u %-9g %#5U %-5G %Am/%Ad/%AY %Cm/%Cd/%CY %Tm/%Td/%TY [%Y] %p\n' -a -quit 2> /dev/null;

for f in a b c d e f g h L k p r s S t u w x O G N;

do

test -$f "$dp" && help test | sed "/-$f F/!d" | sed -e 's#^[\t ]*-\([a-zA-Z]\{1\}\) F[A-Z]*[\t ]* True if#-\1 "'$dp'" #g';

done;

shift;

done

}

Move efficiently between directories.

.

This command adds a couple of extra features to cd, without affecting normal use.

CDPATH use is also unaffected. It introduces and environment variable CDDIR which is used as an alternate home directory.

.

Note: I don't want to alter $HOME because then all my dot files will move.

.

Examples:

.

Change directory to "dir" (using CDPATH if necessary)

.

Change directory to "dir" (containing folder of "file.txt")

This allows you to cut'n'paste, or use

.

CDDIR is unset

Change directory to $HOME

.

CDDIR=/home/flatcap/work

Change directory to /home/flatcap/work

.

For convenience, put the command, and the following, in your .bashrc or .bash_profile

export CDDIR="/home/flatcap/work"

alias cdd="CDDIR=$(pwd)"

For each cpu set mask and then monitor your cpu infos. Temp,load avg. etc.

For example for 2nd cpu or 2nd core

taskset 0x00000002 yes > /dev/null &

For example for 3rd cpu or 3rd core

taskset 0x00000004 yes > /dev/null &

For example for 4th cpu or 4th core

taskset 0x00000008 yes > /dev/null &

Monitor your cpu temp with this command if you want

watch -n1 "acpi -t"

Load avg. from top command

On the machine acting like a server, run:

On the machine acting like a client, run:

where ip.add.re.ss is the ip or hostname of the server.

On the another machine write this command.

pv -r /dev/zero | nc 192.168.1.1 7777

It will show live throughput between two machine.The destination machine ip is at our example 192.168.1.1

You must multiply by 8 for the network calculation.

You must install pv and netcat commands for this commands usage.

Tested on bash, and follows all the rules about leap years.

Finds executable and existing directories in your path that can be useful if migrating a profile script to another system. This is faster and smaller than any other method due to using only bash builtin commands.
