how to move the line after a certain pattern in the file
Hi,
I have a file called /bb/bin/rstrt.
I need to move the line/entry "ccpm_load_shared_memory" after the entry
"initcorp". The problem is that there are several entries for "initcorp" in this file and I need the entry to be moved only after the first instance of "initcorp"
Is there a way to do it via sed or awk ? I am in ksh88 Thanks a lot

The input file looks something like that:

~~~ some entries ~~~
ccpm_load_shared_memory
~~~ some entries ~~~~
initcorp
~~~ some entries ~~~
initcorp
~~~ some entries ~~~
etc....

I need to move the line "ccpm_load_shared_memory" after the first occurence of "initcorp" ....

Is there only one occurrence of the pattern to be moved?

Use nawk or /usr/xpg4/bin/awk on Solaris:

Code:
awk '/ccpm_load_shared_memory/ { next }1
/initcorp/ && !_++ { print "ccpm_load_shared_memory" }
' filename


With some versions of sed (GNU Sed for example):

Code:
sed '0,/initcorp/{
/ccpm_load_shared_memory/d
s/initcorp/&\nccpm_load_shared_memory/
}' filename

Oops, no need for two actions:

Code:
awk '!/ccpm_load_shared_memory/
/initcorp/ && !_++ { print "ccpm_load_shared_memory" }
' filename
