Bash Script - Text (CSV) manipulation

I need a script to manipulate text from my command line. I am on a Mac so the script has to be in bash. usage: [login to view URL] contentfile masterfile column your script will open the contentfile (in my example: [login to view URL]) strip it from LF and CR and will then insert (overwrite if anything should be there) the content of the columns in line 1 to the masterfile, as lines in the specified column. Yes, I know…I am not that good at explaining ;-) So here is an example… Input in terminal: [login to view URL] [login to view URL] [login to view URL] 1 Explaination: script, inputfile, outputfile, column to write in Should produce a file like [login to view URL] File delimiter is and should always be ";" and encoding is UTF8. If you understood what i mean…you´re good!! :-) If not, feel free to ask… Thank you for your efforts!
