$ ledit -h
ledit is a line editor to transform lines in text files.
Matches of the pattern pat are replaced with the replacement string repl.
The syntax of the regular expression is here: https://github.com/google/re2/wiki/Syntax
Inside repl, $ signs are interpreted as in the link below.
https://golang.org/pkg/regexp/#Regexp.Expand
For instance $1 represents the text of the first submatch.
The output file has an ".ledit" appended to the end.
-debug
prints debug info to standard error
-input string
the glob pattern of input text files. Empty string uses stdin and stdout.
-pat string
the regular expresion searched within each line
-repl string
replace text for pattern matched

$ ledit -debug -pat=dog -repl=cat -input=input1.txt
Debug for ledit
glob pattern of input files: "input1.txt"
regular expression pattern : "dog"
replacement expression : "cat"
editing file: input1.txt
line: 2

replaced with: Let's go walk the cat at night.
Example #2
$ ledit -debug -pat="false" -repl="true" -input=input2.html
Debug for ledit
glob pattern of input files: "input2.html"
regular expression pattern : "false"
replacement expression : "true"
editing file: input2.html
line: 4
matched : false
replaced with: true
Example #3
$ ledit -debug -pat=10.0.0.2 -repl=10.0.0.99 -input=input3.toml
Debug for ledit
glob pattern of input files: "input3.toml"
regular expression pattern : "10.0.0.2"
replacement expression : "10.0.0.99"
editing file: input3.toml

The OSX executable is cmd/ledit/ledit.
The Windows 64-bit executable is cmd/ledit/ledit.exe.
sed is a stream editor that is a bit old and cryptic.
You can problem solve your problem with a line editing using sed.
I prefer something easy to use and easy to modify source code.
