Help with sed editor
I am a newbie to Unix and Linux,
Code:
sed "32,45s/[()]//g" file  : 
sed "s/\([0-9]\)-\([0-9]\)/\1\2/g" file

How do we describe these commands in English ? Please help.

Code:
sed "32,45s/[()]//g" file

This line will delete all parenthesis that are in "file"
from line 32 to line 45 (included), and this will be done globally
(so all occurrence in the line will be deleted even if there are more
than 1 parenthesis per line (where 32 <= linenumber <= 45)

Code:
sed "s/\([0-9]\)-\([0-9]\)/\1\2/g" file

this line will suppress all minus sign that are in between 2 figures

Code:
$ cat myt
I[()]A
321-432 654-9879 6754-6564 -
$ sed "s/[()]//g" myt
I[]A
321-432 654-9879 6754-6564 -
$ sed "s/\([0-9]\)-\([0-9]\)/\1\2/g" myt
I[()]A
321432 6549879 67546564 -
$
