1 | Hi, |
2 | |
3 | does anybody know how to check if a package is installed using a script/ |
4 | shell. |
5 | |
6 | Unfortunately eix -I -q CAT/PACK |
7 | produces a return code of 0 irrespectively if CAT/PACK |
8 | is install or not. |
9 | |
10 | I'd like to say |
11 | |
12 | for P in .......; do |
13 | if CHECK_IF_INSTALLED $P; then echo $P; fi |
14 | done |
15 | |
16 | What to replace for CHECK_IF_INSTALLED ? |
17 | |
18 | Many thanks for a hint, |
19 | Helmut. |
