Add a line to a specific spot in a file
Hello,
Simple if you know how, which I don't.
I would like to add a line to file file.env
file.env consists of the following :
line 1-20 here ..
# Begin customizations
ADDED_LINE_TO_GO_HERE
# End customizations
eof
I would like to use a shell script to add the line ADDED_LINE_TO_GO_HERE, but it has to come after # Begin customizations
Any idea how to do this please ?
Cheers,
Dave

tcp-env
tcp-env(1) General Commands Manual tcp-env(1)
NAME
tcp-env - set up TCP-related environment variables
SYNOPSIS
tcp-env [ -rR ] [ -ttimeout ] program [ arg ... ]
DESCRIPTION
The input for tcp-env must be a TCP connection. tcp-env finds out information about that connection, puts the information into several
environment variables as described in tcp-environ(5), and runs program with the given arguments.
Usually tcp-env is run from inetd. It might instead be run from another server that already sets up the right environment variables; if
PROTO is set to TCP when tcp-env is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
whether the input is a TCP connection.
OPTIONS
-r (Default.) Attempt to obtain TCPREMOTEINFO from the remote host.
-R Do not attempt to obtain TCPREMOTEINFO from the remote host.
-ttimeout
Give up on the TCPREMOTEINFO connection attempt after timeout seconds. Default: 30.
