How to pass filename with accentuation and spaces as parameter for shell script file

Asked

I densenveloped a shell script that gets the location of a file and does several manipulations on it, e.g.: ./processes.sh path/file.txt

However, when I send a file name as a parameter that contains spaces it gives an error because it puts ' ' in each space, and so is interpreted by bash as a directory. Ex: path/filename.txt Output: path/filename.txt

How to prevent this?

linux shell parameters

  • What operating system is?

  • @Tony Linux - Ubuntu

  • How are you reading the parameters? You are not using the variables: $N (N > 0) to get the parameters?

  • the reading is correct, I take $1 and put in a variable. When it goes without space it works right.

  • at the beginning of the script IFS=$'\n and in the end unset IFS

  • It works if you put double quotes around the variable? "$@" or "$1"?

    Double quotes also on the call: ./processa.sh "path/nome do arquivo.txt", else each word separated by space will be considered a different parameter: $1, $2, etc...

  • What @Wakim flw makes sense, so I treat the parameter as a single string, I will test tbm if there is any difference between using " or '

    Actually on the call you can use \ or double quotes (anyway the system reads everything as a single variable), in using the variable you should use double quotes to escape the spaces. See: http://www.unix.com/os-x-apple-/208819-file-paths-spaces-variable.html for examples.

The exit was to use double quotes like Wakim and Antonio mentioned, so I’m marking the issue as resolved.
