The shells can parse fields if you change to $IFS to include the right field separators, preferable in a subshell so life is not severly bent for the rest of the shell. In place if ths space and tab separators in $IFS, put your simple delimiters, and then they are separated in terms of 'read', 'for myvar in' or arguments on a command line or shell function call. It's pretty simple, really. Something like "while read f1 f2 f3 f4 f5 f6 f7 f8;do . . . done" suggests itself. You can also subdivide fields in shell using ${varname%} or %%, #, ##. Substrings are a bit more work in ksh, but bash has this more gracefully built in:
