Under unix, define the following: alias lf2cr "cat \!^ | tr '\012' '\015' > \!^.X ; rm -f \!^; mv \!^.X \!^" alias cr2lf "cat \!^ | tr '\015' '\012' > \!^.X ; rm -f \!^; mv \!^.X \!^" You can put these lines in your .cshrc file on your unix account, so they'll always be there. Usage: lf2cr unixfile afterwards, unixfile will contain an apple format text file.
