sed/regexp

[Hanner, Michael [SKY:P062:EXCH]]

Hi,

This is what I want to to:

a:\b.jar:a:\c.jar ---> a:\b.jar a:\c.jar

My question: how do I re-insert a grouping back into my string?

d:\>> echo "a:/b.jar:a:/c.jar" | sed -e"s/:\([A-Za-z]\)/ $1/g"
a:/b.jar :/c.jar

I am unable to re-insert my grouping back into the string.
I've tried \$1, $$1, ....

Thanks

Michael.

Try \1 (backslash one).

C:>echo a:/b.jar:a:/c.jar | sed -e"s/:\([A-Za-z]\)/ \1/g"
a:/b.jar a:/c.jar

Same command works with backslashes in input:

C:>echo a:\b.jar:a:\c.jar | sed -e"s/:\([A-Za-z]\)/ \1/g"
a:\b.jar a:\c.jar

The "$1"-type notation is from perl; the sed way is "\1":

echo "a:/b.jar:a:/c.jar" | sed -e"s/:\([A-Za-z]\)/ \1/g"
