Newbie: replacing strings containing special caracters
Hello,
I am a newbie here and I am just learning using Unix.
I have a dozen scripts that start like that:
#!/bin/ksh
if test $# -eq 0
then
list=short
else
list=$1
fi
DIR=.
DIRTOOLS=../tools
What I want to do is change modify 2 lines in each of these scripts without having to edit the files one by one.
I need to change:
DIR=.
DIRTOOLS=../tools
into:
DIR=../marc2006_qa
DIRTOOLS=/d2/marcdev/tools
There are other occurences of the string "DIR=." and "DIRTOOLS=" elsewhere in each script but only the first ones need to be changed.
Can someone tell me what command I need to type to perform this action?
Thank you so much for your help!

go-path
GO-PATH(7) Miscellaneous Information Manual GO-PATH(7)
NAME
go - tool for managing Go source code
DESCRIPTION
The Go path is used to resolve import statements. It is implemented by and documented in the go/build package.
The GOPATH environment variable lists places to look for Go code. On Unix, the value is a colon-separated string. On Windows, the value
is a semicolon-separated string. On Plan 9, the value is a list.
GOPATH must be set to build and install packages outside the standard Go tree.
Each directory listed in GOPATH must have a prescribed structure:
The src/ directory holds source code. The path below 'src' determines the import path or executable name.
The pkg/ directory holds installed package objects. As in the Go tree, each target operating system and architecture pair has its own sub-
directory of pkg (pkg/GOOS_GOARCH).
If DIR is a directory listed in the GOPATH, a package with source in DIR/src/foo/bar can be imported as "foo/bar" and has its compiled form
installed to "DIR/pkg/GOOS_GOARCH/foo/bar.a".
The bin/ directory holds compiled commands. Each command is named for its source directory, but only the final element, not the entire
path. That is, the command with source in DIR/src/foo/quux is installed into DIR/bin/quux, not DIR/bin/foo/quux. The foo/ is stripped so
that you can add DIR/bin to your PATH to get at the installed commands. If the GOBIN environment variable is set, commands are installed
to the directory it names instead of DIR/bin.
Here's an example directory layout:
GOPATH=/home/user/gocode
/home/user/gocode/
src/
foo/
bar/ (go code in package bar)
x.go
quux/ (go code in package main)
y.go
bin/
quux (installed command)
pkg/
linux_amd64/
foo/
bar.a (installed package object)
Go searches each directory listed in GOPATH to find source code, but new packages are always downloaded into the first directory in the
list.
