Using seq(1) to generate sequences of numbers
The seq(1) command is oft-overlooked. Put simply, it'll generate sequences of numbers.
In its most simple form
seq 100
will return the numbers 1 to 100.
Or perhaps:
seq 10 5 100
which will print the numbers 10 to 100 in increments of 5.
The most obvious use for this is in "for" loops in shell scripts. Other uses might be to generate sequential numbers for tacking onto split file output, or perhaps including in backquotes within a port range for nmap.
