string search and replace

[volcano]

Hi, your help to solve the below problem is appreciated!

There is a sentence (or the whole line sentence) read from a file and stored in a variable by a script. The sentence looks like:

25.05.2007 04:11:01 PM

Now I want to change the sentence to be:

25/05/2007 04:11:01 PM

How can I do such string search and replace in a script?

Thanks.

man sed

Hope This Helps, PH.

hi aau, thanks for your response!
Having searched for this forum again, i also find the following command also works:

echo "25.05.2007 04:11:01 PM" | sed `'s/\./\//g'`

Hi

That works ? Maybe if you remove the back ticks ( ` ) :

echo "25.05.2007 04:11:01 PM" | sed 's/\./\//g'

[gray]# or to avoid escaping the slash ( / )[/gray]

echo "25.05.2007 04:11:01 PM" | sed 's,\.,/,g'

[gray]# or to avoid escaping the period ( . ) too[/gray]

echo "25.05.2007 04:11:01 PM" | sed 'y,.,/,'
