Problem with SED
Hi,
I have to use SED to remove the prefix "219-" from a text file containing phone numbers and I have to remove the ":" as well. I write the following code but it does not seem to work. Can someone help me please? Code:
mohit@mohit-desktop:~$ sed -n s/219-/" "/p corp_phones_bak > noprefix1 mohit@mohit-desktop:~$ sed -n s/:/" "/p noprefix1> noprefix mohit@mohit-desktop:~$ cat no prefix cat: no: No such file or directory cat: prefix: No such file or directory mohit@mohit-desktop:~$ cat noprefix 432-4567 Harrison:Joel:M:4540:Accountant:09-12-1985 432-4587 Mitchell:Barbara:C:4541:Admin Asst:12-14-1995 432-4589 Olson:Timothy:H:4544:Supervisor:06-30-1983 432-4591 Moore:Sarah:H:4500 Dept Manager:08-01-1978 432-4527 Polk:John:S:4520:Accountant:09-22-1998 mohit@mohit-desktop:~$

This works as sed does line by line so by chaining the commands it acts on each line in order. sed -e 's/219-//' -e 's/://' corp_phones_bak eg me@somewhere: ~>more ff 219-444:44 219-44444 me@somewhere: ~>sed -e 's/219-//' -e 's/://' ff 44444 44444

Actually -n causes sed to not print lines by default; it's got nothing with numbers to do. Perhaps the problem is that s/://p will replace only one colon; use s/://gp to replace all colon characters on a line.
