[SOLVED] How can I repeat a character in Bash?

Issue

How could I do this with echo?

perl -E 'say "=" x 100'

Solution

You can use:

printf '=%.0s' {1..100}

How this works:

Bash expands {1..100} so the command becomes:

printf '=%.0s' 1 2 3 4 ... 100

I've set printf's format to =%.0s which means that it will always print a single = no matter what argument it is given. Therefore it prints 100 =s.
