opkg 패키지를 설치하지 않고 버전 정보를 얻는 방법은 무엇입니까?

#!/bin/sh

# command that checks opk version number
#set -e

VERSION=3
version ()
{
  echo
  echo "`basename $1` version $VERSION"
  echo "command that checks opk version number"
  echo

  exit 0
}

usage ()
{
  echo "
Usage: `basename $1` <options> [ files for install partition ]

Mandatory options:
  --opk_file         file name (e.g ./my_package.opk)

Optional options:
  --version             Print version.

  exit 1
}

ar -x $opk_file control.tar.gz    #extract control.tar.gz from .opk
tar -zxvf control.tar.gz ./control > /dev/null 2>&1
# extract control file from control.tar.gz, silent stderr/stdout
cat control |grep Version | sed -e "s/Version:\s*\(\d*\)\D*/\1/"
# grep Version keyword and remove it
rm control
rm control.tar.gz
# clean up

용법:

opkversion.sh --opk_file ./mypackage.opk

명령을 조정하면 sed명령의 필터링 전략이 변경될 수 있습니다(opk 패키지의 버전 번호는 매우 복잡할 수 있음).
