Thanks for the reply but it's not quite what I need.
Code:
root@darkstar:~# ls /var/log/packages/glib2-2.18.1-i486-1gnome224jag
/var/log/packages/glib2-2.18.1-i486-1gnome224jag
root@darkstar:~# installed=$(ls /var/log/packages/glib2-[[:digit:].]* | sed 's/\(-[^-]*-[0-9]\)\(.*\)/\1/g')
root@darkstar:~# echo $installed
/var/log/packages/glib2-2.18.1-i486-1 # installed != 1
root@darkstar:~# ls /var/log/packages/mozilla-firefox-3.0.2-native-1gnome224jag
/var/log/packages/mozilla-firefox-3.0.2-native-1gnome224jag
root@darkstar:~# installed=$(ls /var/log/packages/mozilla-firefox-[[:digit:].]* | sed 's/\(-[^-]*-[0-9]\)\(.*\)/\1/g')
root@darkstar:~# echo $installed
/var/log/packages/mozilla-firefox-3 # installed != 1
As you can see (I forgot to mention), $NAME can also contain a hyphen sometimes so counting them out in the sed doesn't work half the time. $VERSION should always contain digits but may also contain letters. $ARCH could have either numbers and/or letters (native or i486). And $BUILD can also have both.
If I'm working with a package name like "xpaint-2.7.8.1-i486-2", then my old sed works fine.
Hi ,
I have a question. How do I replace 2 words in one line like this
IN CLO07 INDEX IN CLOIX07

IN CLO07_S02 INDEX IN CLOIX07_S02
But one thing to remember is that there are lots of words like CLODM001 .
So the only matching pattern is "IN CLO"

APT-MARK(8) APT APT-MARK(8)NAME
apt-mark - mark/unmark a package as being automatically-installed
SYNOPSIS
apt-mark [-hv] [-f=FILENAME] {auto | manual | showauto | showmanual} package...
DESCRIPTION
apt-mark will change whether a package has been marked as being automatically installed.
When you request that a package is installed, and as a result other packages are installed to satisfy its dependencies, the dependencies
are marked as being automatically installed. Once these automatically installed packages are no longer depended on by any manually
installed packages, they will be removed by e.g. apt-get or aptitude.
auto
auto is used to mark a package as being automatically installed, which will cause the package to be removed when no more manually
installed packages depend on this package.
manual
manual is used to mark a package as being manually installed, which will prevent the package from being automatically removed if no
other packages depend on it.
hold
hold is used to mark a package as hold back, which will prevent the package from being automatically installed, upgraded or removed.
The command is only a wrapper around dpkg --set-selections and the state is therefore maintained by dpkg(1) and not effected by the
--filename option.
unhold
unhold is used to cancel a previously set hold on a package to allow all actions again.
showauto
showauto is used to print a list of automatically installed packages with each package on a new line. All automatically installed
packages will be listed if no package is given. If packages are given only those which are automatically installed will be shown.
showmanual
showmanual can be used in the same way as showauto except that it will print a list of manually installed packages instead.
showhold
showhold is used to print a list of packages on hold in the same way as for the other show commands.
OPTIONS -f=FILENAME, --file=FILENAME
Read/Write package stats from FILENAME instead of the default location, which is extended_status in the directory defined by the
Configuration Item: Dir::State.
-h, --help
Show a short usage summary.
-v, --version
Show the program version.
-c, --config-file
Configuration File; Specify a configuration file to use. The program will read the default configuration file and then this
configuration file. If configuration settings need to be set before the default configuration files are parsed specify a file with the
APT_CONFIG environment variable. See apt.conf(5) for syntax information.
-o, --option
Set a Configuration Option; This will set an arbitrary configuration option. The syntax is -o Foo::Bar=bar. -o and --option can be
used multiple times to set different options.
FILES
/var/lib/apt/extended_states
Status list of auto-installed packages. Configuration Item: Dir::State::extended_states.
SEE ALSO apt-get(8),aptitude(8),apt.conf(5)DIAGNOSTICS
apt-mark returns zero on normal operation, non-zero on error.
