2 de ago. de 2023 · Versions of sed that support the -i option for editing a file in place write to a temporary file and then rename the file. Alternatively, you can just use ed. For example, to change all occurrences of foo to bar in the file file.txt, you can do: echo ',s/foo/bar/g; w' | tr \; '\012' | ed -s file.txt. Syntax is similar to sed, but certainly not ...

The advantage of JScript over VBScript is it can be easily combined with batch in a single script, making the utility easier to use in a batch or command line context. A robust hybrid JScript/batch utility called REPL.BAT is available.
The odd thing is the lines work individually out of the script. but when inside the script i get this. sed: -e expression #1, char 17: unknown option to `s'. I am using '' when it can take it literally and "" when it needs to print the variable. It seems to me this should be working.
I created a sed script that cleans up the file (there's lots of "dirty" formatting like double spaces and spaces before/after commas). The problem is the Zip with the period.

MikhailVS's answer mentions the technique, put into a concrete example here:
