Sed commands in several lines 2

[atojaf]

Could you please tell me how to separate these commands in several lines. Each line starting with the -e. I am running this on a Korn shell. thanks again.


cat test.txt | sed -e '/log/ s/log/ /g' -e '/car/ s/car/ /g' -e '/GO/ s/GO/ /g' -e '/ON/ s/ON/ /g'

sed '
/log/s/log/ /g
/car/s/car/ /g
/GO/s/GO/ /g
/ON/s/ON/ /g
' test.txt

Hope This Helps, PH.

isn't
sed -e '/log/ s/log/ /g' the same as
sed -e 's/log/ /g' ?

and
sed -e 's/log/ /g' the same as
sed 's/log/ /g' ?

I would use:

sed 's/log/ /g;s/car/ /g;s/GO/ /g;s/ON/ /g' test.txt

which can be reduced father with ORs:

sed 's/\(log\|car\|GO\|ON\)/ /g' test.txt

Hi

The -e is require only if you write multiple commands as separate command line parameters, as in atojaf's example. That way without -e the second and subsequent codes would be treated as filenames.

And there is no need to capture the matched expressions with parenthesis ( () ).

sed 's/log\|car\|GO\|ON/ /g' test.txt

[gray]# or abit more readable in GNU sed[/gray]
sed -r 's/log|car|GO|ON/ /g' test.txt

Hm. sed -r looks good!
I'll have to remember that option - good tip.
