from -- Command Generate list of numbers, for use in loop from start to stop [ by incr ] from prints a list of integers on the standard output, one per line. It prints beginning with start, and then prints successive numbers incrementing by incr (default, one) the previous number. It continues until the generated value matches or exceeds stop. Each of start, stop, and optional incr is a decimal integer with an optional leading `-' sign. Typical uses of from include generating a file of numbers and generating a loop index for the shell. The following example creates special files for eight terminal ports: for i in `from 0 to 7` do /etc/mknod /dev/hs0$i c 7 $i done See Also commands, ksh, sh Diagnostics from prints an error message if the generated list is empty.
