I call this pmls

#!/usr/bin/zsh
echo "\n\n"
echo "Would you like to see (b)inaries, (d)ocs, e(x)amples, or Enter for all?"
read CHOICE
echo "\n\n"
if [ $CHOICE = "b" ] ; then
    pacman -Ql $1 | grep --color=auto 'bin'
else
    if [ $CHOICE = "d" ] ; then
        pacman -Ql $1 | grep --color=auto 'doc'
    else
        if [ $CHOICE = "x" ] ; then
            pacman -Ql $1 | grep --color=auto -i 'sample\|example'
        else
            pacman -Ql $1 | more
        fi
    fi
fi

usage: pmls <package_name>

I use it to see only the binaries, docs, or examples. Pressing enter/return at the prompt displays everything.

Any particular reason to use nested 'if's? Wouldn't 'case' do? getopt/s?

Edit: typo.

or at least "elif" if you are going to stick with ifs.

"Self-made"

If someone wants' to "make it better" then I won't criticize.

karol · 2014-12-06 20:52:56

I'd go with 3 separate shellscript functions e.g.

$ type pmlsb
pmlsb is a function
pmlsb ()
{
    pacman -Ql $1 | grep --color=auto 'bin'
}

Note that there is no need to use yaourt to remove AUR packages. Pacman doesn't care where a package originally came from, once it is installed, it is in pacman's database.

Also, unless yaourt has changed, the update aur packages doesn't actually update aur packages. You need to use -Syua to update all package including aur packages.

tzoi516 · 2014-12-10 20:49:17

I appreciate the feedback. I also just want 1 script vice more. Here's my update:

#!/usr/bin/zsh

echo "Would you like to see (b)inaries, (d)ocs, e(x)amples, or Enter for all?"

read CHOICE
if [ $CHOICE = "b" ] ; then
    pacman -Ql $1 | grep --color=auto 'bin'
elif [ $CHOICE = "d" ] ; then
    pacman -Ql $1 | grep --color=auto 'doc'
elif [ $CHOICE = "x" ] ; then
    pacman -Ql $1 | grep --color=auto -i 'sample\|example'
else
    pacman -Ql $1 | more
fi

jasonwryan · 2014-12-10 20:53:14

Look at using a case statement...

tzoi516 · 2014-12-10 21:13:13

OK, a case version

#!/usr/bin/zsh

echo "Would you like to see (b)inaries, (d)ocs, e(x)amples, or Enter for all?"

read CHOICE

case $CHOICE in

b)
    pacman -Ql $1 | grep --color=auto 'bin'
    ;;
d)
    pacman -Ql $1 | grep --color=auto 'doc'
    ;;
x)
    pacman -Ql $1 | grep --color=auto -i 'sample\|example'
    ;;
*)
    pacman -Ql $1 | more

Thanks for this. Gonna update my script when im at my computer.

juiko · 2014-12-22 03:12:24

i use this when im not sure of the name of a program ...

#!/usr/bin/env perl

use strict;
use warnings;
use feature 'say';

use File::Find;

find sub{ say $File::Find::name if /$ARGV[0]/ }, $_ for split ':', $ENV{PATH};

i call it fip (find in path) ...

example:

fip python
=> 
/usr/bin/python2
/usr/bin/python3-config
/usr/bin/python2.7-config
/usr/bin/ipython
/usr/bin/python3
/usr/bin/python2.7
/usr/bin/ipython2
/usr/bin/python2-config
/usr/bin/python3.4m
/usr/bin/python
/usr/bin/python-config
/usr/bin/python3.4-config
/usr/bin/python3.4m-config
/usr/bin/ipython3
/usr/bin/python3.4

karol · 2014-12-22 04:12:27

Is it different from

$ type python
python is /usr/bin/python
$ which python
/usr/bin/python

? Do you want auto-completion?
Depending on the shell you're using and the settings you enabled, you can e.g. <tab> twice:

$ python <tab> <tab>
python             python2-config     python3            python3.4-config
python-config      python2.7          python3-config     python3.4m
python2            python2.7-config   python3.4          python3.4m-config

juiko · 2014-12-26 03:22:39

Yeah, i guess my script is mostly a bad copy of autocompletion .

It will give more results than autocompletion though, for example with python as the search string it will show ipython, while autocompletion will only show strings that match /^python/

Take a ride on a ttycycle

#!/bin/bash
[[ -n "${1}" ]] && INTERVAL="${1}" || INTERVAL="10"
while true; do
  for (( i=2; i<7; i++ )) do sleep "${INTERVAL}"; chvt "$i" & done
done

Note, this ttycycle has no brakes (while true), you might want to set a timeout:

timeout "${TIMEOUT}" ttycycle

EDIT: Added an INTERVAL setting (number of seconds)

$ for (( i=2; <i<7; i++ )) do sleep 10; chvt "$i" & done
-bash: ((: <i<7: syntax error: operand expected (error token is "<i<7")

Even when I fixed it, I get

Couldn't get a file descriptor referring to the console

kokoko3k · 2014-12-29 12:02:58

I've still to test it, but this is my poor man's dropbox versus my brand new raspberry pi after i've set up ssh key authentication.
Beware that the first sync cannot be done in batch mode, but probably in manual mode.

#!/bin/bash
LDIR="/home/koko/Dropbox/"
RDIR="/root/unison"
RHOST="pi"
RPORT="40022"

while true ; do
    unison -batch -prefer newer -times $LDIR ssh://root@$RHOST/$RDIR -sshargs "-p $RPORT -o cipher=arcfour"
    timeout 60 inotifywait -r -e modify,move,create,delete $LDIR
done

Another thing comes to mind.
Any reason why the unison version in arch is so outdated?
the new 2.48 unison version has a wonderful copyonconflict option missing in the arch package

typo; fixed.

Perhaps you have to actually initiate the ttys (ctrl+alt+f2~f7) before you can cycle between them?

I'm using this in a live session on a laptop which is monitoring several aspects of a very large backup to a desktop.

On tty1 I initiated a large backup (30GB disk image) from my old winblow$ laptop (arch live session) to my arch desktop over ssh (over wifi).
On tty6 I started sensorsweep (over ssh) for the desktop.
On tty5 I started powertop (over ssh) for the desktop.
On tty4 I started top (over ssh) for the desktop.
On tty3 I started powertop for the laptop (no sensors available).
On tty2 I started top for the laptop and ttycycle in the background:

ttycycle & top

for (( i=2; i<7; i++ )) specifies to cycle tty2 through tty6; tty1 is skipped intentionally (nothing to see there).

Subsequently, sshbeam

#!/bin/bash

if [ -n "$3" ]; then

  if [ ! -d ~/sshfs-beam.in ]; then

    mkdir ~/sshfs-beam.in
    sshfs "$2"@"$1":/home/"$2"/Public ~/sshfs-beam.in
    cp "$3" ~/sshfs-beam.in/
    sleep 1
    fusermount -u ~/sshfs-beam.in
    rm -rf ~/sshfs-beam.in

  else

    if [ -n "$(mount | grep ~/sshfs-beam.in)" ]; then

        cp "$3" ~/sshfs-beam.in/

    else

      sshfs "$2"@"$1":/home/"$2"/Public ~/sshfs-beam.in # sshfs "$1":/home/"$2"/Public ~/sshfs-beam.in
      cp "$3" ~/sshfs-beam.in/

    fi

  fi

else

  printf "\n #$0 ip user file\n"

fi

For example, I tested how long it takes to sshbeam a large file over a zero-distance connection.

time sshbeam 127.0.0.1 quequotion ~/path\ to\ dvd.iso
quequotion@127.0.0.1's password: 

real	0m34.718s
user	0m4.149s
sys	0m0.480s

Minus the password entry (~4sec), sshbeam was only about two seconds slower than an ordinary copy.

time cp ~/path\ to\ dvd.iso ./

real	0m28.997s
user	0m0.723s
sys	0m1.845s

::UPDATE:: Cleanup and help, tested over a short hop (local wifi).

time sshbeam 192.168.1.8 someone /path/to/file/with/size/699986824.mp4 
someone@192.168.1.8's password: 

real	5m11.709s
user	0m0.631s
sys	0m0.066s

::edit:: the chinese charater was probably confusing; even I can't really read that but I think it was the "downloads" folder.

Link manager for ptpb.pw and transfer.sh (https://github.com/ShadowKyogre/pb_manager <- decided to put it here in case I actually need to make it a full fledged project)

It works, but, I'm a little stuck on where I should be storing the *.tsv files since I'm using this to help manage public links since I'm using SyncThing. So I'm stuck between being specified via commandline args or via a config file.
