delete a pattern
 

Hi

My file has patterns which look like

string1.1
string2.1
string 3.1
...
string 100.1....
and so on

I would like to replace them to
string1
string2
string3
string100

Basically removing .1 extension
I tried deleting the .1 pattern by using

sed /.1/d filename> newfile

But it deleted the entire line of string.

Please advise.

Hence you do not wish to delete, you wish to replace with nothing. Try the s/// construct instead

Thanks for inputs!

It rectified all other strings but didnt work for the 1st string entry.

(It replaced string1.1 to just strin)
Part of my result :

edit

sorry for double post.

Try with:

if it occurs only at the end of the line you can use the following:
sed 's/\.1$//'

Thanks for correcting!
