Removing single line comments in a file
How do I manage to remove single comments starting with /*......*/
and
Anyway, I mean it could be on a separate line or after some equation, for example.
I was thinking something like:
s/\/\*.*\*\///g'

sed -e 's|/\*.*\*/||g' => to remove /* ... */
sed -e 's|//.*||g' => to remove //...
sed -e 's|/\*.*\*/||g' -e 's|//.*||g' => to remove both /* ... */ and //...
Example:
sdlcb@ubuntu:~$ cat file
jksdjskjdsd /* jdskdskd */
jdskdjsd // ksldksldsdks
uiiu
sdlcb@ubuntu:~$ sed -e 's|/\*.*\*/||g' -e 's|//.*||g' file
jksdjskjdsd
jdskdjsd
uiiu

Or, if you don't like the look of the picket, you can change the separator and also use character classes to avoid having to avoid everything:
's|/[*].*[*]/||g'
Note: The valid separator replacement varies slightly on OS.
