Hi,
sorry a bit off-topic,
sed -e 's/\(<[^ ]*>\)\([ ]*\)\(<[^ ]*>\)/\3\2\1/g'
GNU Linux is cool
Linux GNU cool is
No here ...
I don't know why
$ echo "GNU linux is cool" | sed -e 's/\(<[^ ]*>\)\([ ]*\)\(<[^ ]*>\)/\3\2\1/g'
GNU linux is cool
It doesn't work.
Remove "<" and">", from substitution, and sustitute * by "\+", and
you can use " *" without have to use "[ ]*"
I read it from a book and didn't get why use "<"
sed -e 's/\([^ ]\+\)\( \+\)\([^ ]\+\)/\3\2\1/g'
Thanks, I tried, sed -e 's/\([^ ]\+\) \([^ ]\+\) \([^ ]\+\)/\3 \2 \1/g'
or using extended regular expressions, you can remove all escape stuff :
sed -re 's/([^ ]+)( +)([^ ]+)/\3\2\1/g'
Ha ... I didn't realize the -r can be used.
sed -re 's/([^ ]+) ([^ ]+) ([^ ]+)/\3 \2 \1/g'
I hope this help
Thanks again for your help. I was a bit lost when reading other's work,
... now better. ^_^
