sed command

Hi, I need to use appropriate sed command to replace all the
string "male" to "female" in file: myfile. I'm a Unix beginner and
confused. Thanks.

Try this:
sed 's/male/female/g' <input_file >output_file

This script will change all occurences of "male". If you leave out the "g" it will change the first occurence of "male" only.

Read some tutorial.


Regards

this also would change
xxmalezz to xxfemalezz
do you want that ?
using sed and little more precision
s/\<male\>/fe&/g
(could also be case sensitive )
btw
sed ... < input > output
and
sed ... input > output
are the same

NOT REALLY SURE

/\<male\>/s//fe&/g

COULD BE FASTER, not tested !
