Hello,

I have a log file, which I want to use as a word list. Problem is, there's no space between the words and the numbers to which the words are linked.

For instance, I need to change

called20:12,18

to

called 20:12,18

by adding a space between the words and the numbers.

sed's info file tells me that replace-strings get interpreted litterally on the right hand side.

Thus, as info telle me, sed s/[a-zA-Z][0-9]/[a-z][A-Z]\ \[0-9]/g testfile produces "calle[a-z][A-Z] [0-9]0:12,18"

Can someone tell me how I can search my file for all instances of letter-then-number, and replace them with letter-then-space-then-number?

Thank you very much.

Just search for a subpattern containing one or more alphabetics, such as ([a-zA-Z]+), then replace it with the subpattern plus a space. That presumes that your example always represents your data.

Here's a copy of a CLI screen

Ooble

Just to clarify:

When you want to keep certain sections of the document you're running the regex on, you enclose them in parentheses (brackets - ( and ) ), as DaWei shows. You then use these by using "\1", "\2" etc. in the replace string.
