My little script for pkg search

grissiom · 05-18-2009, 01:32 AM

The first one is to search the package name with certain patterns:
pkgls:

Code:

#!/bin/zsh
# file name: pkgls

usage="Usage: pkgls [options] <exp>
ls the package name with pattern <exp>

pkgls use grep to filter the names. See man grep for more info about options
and expressions. pkgls already set --color=auto --no-filename for grep."

[[ $ARGC -eq 0 || $1 == '--help' ]] && {echo $usage; exit 2}

packages_path='/var/log/packages'

cd ${packages_path} 2>/dev/null || {echo ${packages_path}' not accessible'; exit 1}
echo -e '\e[0;32;1mmtime:           package name:\e[0m'
ls -hcogG1 --time-style=long-iso --sort=time | \
sed -e '1d' -e 's/ \{1,\}/ /g' | cut -f4- -d' ' | \
grep --color=auto --no-filename $@ -

The second one is search a file name belongs to which package:
pkgrep

Code:

#!/bin/zsh
# file name: pkgrep

packages_path='/var/log/packages'
ls='/bin/ls'

cd ${packages_path} 2>/dev/null || {echo ${packages_path}' not accessible'; exit 1}
grep --color=auto --with-filename $@ *

#echo
#echo 'in script:'
#echo
#(cd /var/log/scripts && grep --color=tty $@ *)

pkgless

Code:

#!/bin/zsh
# file name: pkgview

usage="Usage: pkgview [options] <exp>
view the info and content of package matching pattern <exp>

pkgview use grep to filter the names and view(part of vim) for viewing the info
so you don't have write permittion to the files. See man grep for more info
about options and expressions."

[[ $ARGC -eq 0 || $1 == '--help' ]] && {echo $usage; exit 2}

packages_path='/var/log/packages'
ls='/bin/ls'

cd ${packages_path} 2>/dev/null || {echo ${packages_path}' not accessible'; exit 1}

file_names=($($ls | grep --color=auto --no-filename $* - ))
[[ $file_names == '' ]] && {echo 'no package found'; exit 2}
view -p ${file_names}

These are very easy and small scripts.The main feature is that you can take the advantage of grep directly!~ I found them useful in some cases so I put them here. Attachment is the screen shot.

Very handy, thanks.

I made a modification so both scripts would be merged into one.

Code:

#!/bin/sh
# file name: pkgsearch
# Based on pkgls and pkgrep by grissiom
# http://www.linuxquestions.org/user/grissiom-406049/
# June 17, 2009

pkgls() {

# file name: pkgls

(cd ${packages_path} 2>/dev/null || echo ${packages_path}' not accessible' || exit 1
echo -e '\e[0;32;1mmtime:           package name:\e[0m'
ls -hcogG1 --time-style=long-iso --sort=time --color=always | \
sed -e 's/[rwxs-]\{10\} *[0-9]* *[0-9.KMG]* *//'  | \
grep --color=always $@ )
	}

pkgrep() {

# file name: pkgrep

(cd ${packages_path} 2>/dev/null || echo ${packages_path}' not accessible' || exit 1
grep --color=always $@ *)

#echo
#echo 'in script:'
#echo
#(cd /var/log/scripts && grep --color=tty $@ *)
	}


packages_path='/var/log/packages'


while getopts ":lg" Option
do

case $Option in
    l     ) shift;pkgls $@;;
    g     ) shift;pkgrep $@;;
    *     ) echo "Unimplemented option chosen.";;   # DEFAULT
  esac
done

shift $(($OPTIND - 1))

A while ago a whipped up a quick script that was basically just "ls /var/log/packages | grep $1," but I think I like yours more. Particularly pkgrep.

Thanks. :-)

Nice. I like it. Remind me of something like pkg_info in FreeBSD

grissiom · 06-18-2009, 08:20 AM

I'm very happy you like those little stuff

I also made some local changes and add a pkgless script. Here are they

I will update the first post as well)

pkgls:

Code:

#!/bin/zsh
# file name: pkgls

usage="Usage: pkgls [options] <exp>
ls the package name with pattern <exp>

pkgls use grep to filter the names. See man grep for more info about options
and expressions. pkgls already set --color=auto --no-filename for grep."

[[ $ARGC -eq 0 || $1 == '--help' ]] && {echo $usage; exit 2}

packages_path='/var/log/packages'

cd ${packages_path} 2>/dev/null || {echo ${packages_path}' not accessible'; exit 1}
echo -e '\e[0;32;1mmtime:           package name:\e[0m'
ls -hcogG1 --time-style=long-iso --sort=time | \
sed -e '1d' -e 's/ \{1,\}/ /g' | cut -f4- -d' ' | \
grep --color=auto --no-filename $@ -

pkgrep

Code:

#!/bin/zsh
# file name: pkgrep

packages_path='/var/log/packages'
ls='/bin/ls'

cd ${packages_path} 2>/dev/null || {echo ${packages_path}' not accessible'; exit 1}
grep --color=auto --with-filename $@ *

#echo
#echo 'in script:'
#echo
#(cd /var/log/scripts && grep --color=tty $@ *)

pkgless

Code:

#!/bin/zsh
# file name: pkgview

usage="Usage: pkgview [options] <exp>
view the info and content of package matching pattern <exp>

pkgview use grep to filter the names and view(part of vim) for viewing the info
so you don't have write permittion to the files. See man grep for more info
about options and expressions."

[[ $ARGC -eq 0 || $1 == '--help' ]] && {echo $usage; exit 2}

packages_path='/var/log/packages'
ls='/bin/ls'

cd ${packages_path} 2>/dev/null || {echo ${packages_path}' not accessible'; exit 1}

file_names=($($ls | grep --color=auto --no-filename $* - ))
[[ $file_names == '' ]] && {echo 'no package found'; exit 2}
view -p ${file_names}

And thanks Andy Alkaline. I will consider combine them into a single script in the future
