Is there a way to repeat something 30 times in terminal?

Loops are your friend. This following example will print Hello x where x is a number:

for x in `seq 1 10`
do
        echo Hello $x
done

The output of that is as follows:

Hello 1
Hello 2
Hello 3
Hello 4
Hello 5
Hello 6
Hello 7
Hello 8
Hello 9
Hello 10

Change the sequence parameters to 1 30 and that would happen 30 times. Once you change that, simply replace the echo line with the command you want to execute thirty times. So, for instance:

for x in `seq 1 30`
do
        <your command>
done

Replace <your command> with the command you want executed and you're good to go.

Save that as a shell script and simply execute it from the command line:

sh <path to script>

how bout...

#!/bin/bash
x=1
while [ $x -le 30 ]
do
  echo "Welcome $x times"
  x=$(( $x + 1 ))
done

There's also estabishing as in for i in 1 2 3 4 5 6 7 etc.. and COUNT, COUNTER.. ohhh so many ways

As the Perl motto goes, "There's more than one way to do it."

For the OP: you can take my script (and Dysfunction's) and make it into a command instead of a script. Mine would look like so:

for x in `seq 1 30` ; do echo $x ; done

That's helpful if you don't want a script.

Would

echo 'How many times?'
read numtimes
for x in numtimes
do
touch file $filenum.txt
done

work?

ok, it does.(i tested it)
However, the file incrementing did not. How would i do this? I want to make as many files as possible.

Ahhh, got it. That was confusing.

#! /bin/bash

echo "Ready to crash your computer?"
read yes
echo "You entered yes. Why?"
mkdir ~/Desktop/Files
cd ~/Desktop/Files
echo 'How many times?'
read x
y=99
while [ $y -le $x ]
do
  touch $y.txt
  y=$(( $y + 1 ))
done

Don't put a high number in.
