Substitution with sed
I have a file with some numbers having single quotes around them which I want to remove.

i.e. '923930' -> 23930

If it can be done without using sed thats fine. I have tried with sed but can't think how to replace this pattern on only the numbers

Code:
sed 's/\'([0-9]+)\'/$1/g' file

or

sed 's/\'([0-9][0-9]*)\'/$1/g' file

Thanks, I get the error:

syntax error at line 2: `(' unexpected

also can I ask why `sed 's/\'([0-9])*\'/$1/g' input file` would not work?

You need to use double quotes around the sed script in this case..

sed "s/'\([-+]\{0,1\}[0-9][0-9.]*\)'/\1/g" file works but i was wondering why the other sed command gives me the following error:

Code:
 
sed "'s/\'([0-9][0-9]*)\'/$1/g'" newscript2

Unrecognized command: 's/\'([0-9][0-9]*)\'//g'

Code:
sed "s/\'([0-9][0-9]*)\'/$1/g" newscript2

instead of

Code:
sed "'s/\'([0-9][0-9]*)\'/$1/g'" newscript2
