And if your not on a BSD system or derivative which has fold try the
following awk prog:
-----------------------------------------------------------
#
#########################################################
#
#  This script folds long lines into 60-character lines.
#  A "\e" is appended to indicate that the line was
#  folded, and the residue is then processed.  It is
#  assumed that the input file does not contain tabs.
#  The input line is only broken on spaces.
#
#  To run this script:
#     awk -f fold.script filename
#
#########################################################
#
BEGIN   {
        N = 57  # fold at column 57
}

{       if ((n = length($0)) <= N)
                print                   # fold is unnecessary
        else    {
                split($0,word);
                line = "";
                cnt = 0;
                for (i = 1; length(line) < N; i++)      {
                        line = line " " word[i];
                        cnt = cnt + 1;
                }
                line = line " ";
                if (cnt == NF)
                        printf "%s\n", line
                else    {
                        printf "%s\e\n", line;
                        line = "";
                        for (i = cnt+1; i <= NF; i++)   {
                                line = line " " word[i];
                                cnt = cnt + 1;
                        }
                        printf "%s\n", line
                }
        }
}

You may want to modify it to be more flexible but it does the basic
work already.

enjoy,
