Linux Commands: Print numeric sequences


seq-Linux Command

seq command- Print numeric sequences

Syntax: seq [options]... [FIRST [STEP]] LAST...

Description: These utilities emit a sequence of integers, with a user-selectable increment.
The default separator character between each integer is a newline, but this can be changed with the -s option.
bash$ seq 5
1
2
3
4
5

bash$ seq -s : 5
1:2:3:4:5
Both jot and seq come in handy in a for loop.

Example:
# Create a set of 10 files,
#+ named file.1, file.2 . . . file.10.
COUNT=10
PREFIX=file

for filename in `seq $COUNT`
do
touch $PREFIX.$filename
# Or, can do other operations,
#+ such as rm, grep, etc.
done
