seq: Linux Commands HowTo
seq: Print numeric sequences
Print a sequence of numbers to standard output
Syntax
seq [options]... [FIRST [STEP]] LAST...
Options
-f FORMAT
--format=FORMAT
Print all numbers using FORMAT; default `%g?. FORMAT must contain
exactly one of the standarding float output formats `%e?, `%f?, or
`%g?.
-s STRING
--separator=STRING
Separate numbers with STRING; default is a newline. The output
always terminates with a newline.
-w
--equal-width
Print all numbers with the same width, by padding with leading
zeroes. (To have other kinds of padding, use `--format?).
`seq? prints the numbers from FIRST to LAST by STEP.
By default, FIRST and STEP are both 1, and each number is printed on its own
line. All numbers can be reals, not just integers.
Examples
Produce a sequence of numbers from 1 to 100
$ seq 100
You can also produce a sequence with the for command
for ((myseq=0; myseq<50; myseq ))
do
echo The sequence is ${myseq}
done
fi
