sed regex


Below is the extract of one file where there are many similar entries.

Code:
$cat file1
| weblogic | bakejo | user1@example.com | user1@example.com | managed_server_lonlx10404.example.com_1_lonlx10404.example.com:8380 | managed_server_lonlx20491.example.com_2_lonlx20491.example.com:8380 |
| weblogic | bakejo | user1@example.com | user1@example.com | lonlx10404.example.com | lonlx20491.example.com |
I want to replace a pattern starting with managed and ending with second .com ( for example "managed_server_lonlx20491.example.com_2_lonlx20491.example.com") with only "managed".

i.e. final output should look like this
Code:
$cat file1
| weblogic | bakejo | user1@example.com | user1@example.com | managed:8380 | managed:8380 |
| weblogic | bakejo | user1@example.com | user1@example.com | lonlx10404.example.com | lonlx20491.example.com |
I tried to use sed

$sed -ne 's/managed_server_*_2_*.com/managed/p' file1

which did not work. I am sure taht I am not using correct regex. Please help.

Hi,

You are using a star (*) to capture a range, that should be dot star (.*):
Code:
sed 's/managed_server_.*_2_.*\.com/mamaged/g' infile
If you do want to look for dot com (.com) that dot needs to be taken literally and thus be escaped (\.com).

Hope this helps.
