I want to start developing in c#, however I use Linux and VSCode for development and VSCode doesn't run the code due to some error that I can't find an answer to, so I decided with the help of this link (Run C# code on linux terminal) to make a bash script that does this part of the code:

mcs -out:hello.exe hello.cs

mono hello.exe

I made it like this so far:

#Trial

function cs_compiler(){

mcs -out:$2 $1

mono $2

}

It does work however I want to make it so that $2 (the second parameter) is automatically named after the $1(the first parameter), thus I needn't write $2's value and just write $1 create an exe with the same name and run that exe with mono. The second thing I want is to check if the exe form of the cs file already exists, if so just run it (mono) without doing mcs-out.

I'm sorry if this is of inconvenience, I'm new to stackoverflow and coding.

From man basename:

Strip directory and suffix from filenames

Sadly you have to know suffix in advance to use it. So:

cs_compiler() {

    local infile outfile

    infile="$1"

    outfile="$(dirname "$1")/$(basename "$1" .cs)"

    mcs -out:"$outfile" "$infile"

    mono "$oufile"

}

1. Quote your variables.


2. Indent your code

But maybe better would be to remove the part after dot:

infilename=$(basename -- "$1") # some temp variable

outfile="$(dirname "$infile")/${infilename##*.}"

See this post on how to extract filename from files.
