I have git svn command like this:
git svn log --limit=1 --oneline
It will output oneline like this:
r12345 | <anything, as it is svn comment inputted by svn-user>
I am trying to pipe in sed command so that I get the 12345
only, however, I can't get it to work.. There are a lot of errors and the current one is parenthesis not balanced
my last command was as follows:
git svn log --limit=1 --oneline | sed -e 's/r\(0-9) |*/\1/'
I've googled and the sed documentation isn't quite clear… I am not very good with regex and my best experience is with git --grep
which is simplified regex with good documentation.
Environment is MacOSX terminal, if matters.
EDIT:
sed -n 's/r\(0-9*\)/\1/
works, but returns empty string.

Here's a regex-free solution, because
(take it with a grain of salt)
You can use
cut
twice:The first cut (
cut -d ' ' -f 1
) sets space as column delimiter and selects only the first column, sor12345
. The second cut (cut -c 2-
) selects character at position 2 and following (2-
).
