[SOLVED] Replace illegal characters for file operations in linux server in a character string

Issue

I have a string name that will generate a file name as paste(name, ".pdf", sep="")

This file will then be moved to another directory after completion.

I would like to proactively avoid any characters in name that might cause errors in file operations like whitespace , \, [], other characters like !"§$%&/()= and any others by replacing them. Special characters in German like öäüß should not cause problems and should be allowed.

Since name is a user input I can't know beforehand what a user might input as character which will then cause problems.

Which characters will give me errors?

Is there any solution or regex to do this without explicitly running each character with sub for example df$name<-sub(" ", "_", df$name)

Solution

The R package {fs} provides the function fs::path_sanitize(). You probably want to check it out. https://fs.r-lib.org/reference/path_sanitize.html
