How repeat same string n times. For example, let's repeat "HAGE" 256 times.
$ printf "%256s\n" | sed 's/ /HAGE/g'
$ echo HAGE{,}{,}{,}{,}{,}{,}{,}{,}
$ yes HAGE | head -n 256
$ sed -r ':a s/$/HAGE/; /(HAGE){256}/!ba' <<<""
$ seq 256 | sed 's/.*/HAGE/g'
$ perl -le 'print "HAGE" x 256'
$ ruby -le 'puts "HAGE" * 256'
$ egison -T -e '(take 256 (repeat1 HAGE))'
$ node -e 'console.log("HAGE".repeat(256))'
$ python <<<'print "HAGE" * 256'
php -R 'print str_repeat("HAGE", 256)."\n";' <<<""
anything else?
