Question on Aptitude search pattern

Akhran · 02-09-2006, 10:55 AM

I'm searching for a package called 'libstdc++2.10-glibc2.2'.

Code:

aptitude search libstdc++2.10-glibc2.2

or

Code:

aptitude search 'libstdc++2.10-glibc2.2'

or

Code:

aptitude search "libstdc++2.10-glibc2.2"

does not return me any result.

However, if I use

Code:

aptitude search libstdc.*2.10-glibc2.2

the package is found.

Any reason why the first three commands do not return the expected package?

Thanks !

Code:

vi +/"^Search Patterns" /usr/share/doc/aptitude/README

Quote:

Most textual searches (for package names, descriptions, etc) are performed using
case-insensitive regular expressions. This means that you must backslash-escape
regular expression metacharacters [11] in searches (for instance, to find
``g++'', you should use the pattern ``g\+\+'').

you have to issue:

Code:

aptitude search "libstdc\+\+2.10-glibc2.2"
