The str_repeat function is a commonly used function that allows you to print/generate a string that is filled with a number of common patterns. For example:
str_repeat(3, “Hello “) gives “Hello Hello Hello ”
The following is a quick Windows Batch Script that does the same thing:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | @echo off setlocal enableDelayedExpansion if [%1]==[] goto help if [%2]==[] goto help set s= for /L %%v in (1,1,%1) do ( set s=!s!%~2 ) echo !s! goto :eof :help echo Usage %0 count pattern |
@echo off
setlocal enableDelayedExpansion
if [%1]==[] goto help
if [%2]==[] goto help
set s=
for /L %%v in (1,1,%1) do (
set s=!s!%~2
)
echo !s!
goto :eof
:help
echo Usage %0 count patternFor example:
1 2 3 4 5 6 7 | $ str_repeat.cmd 3 * *** $ str_repeat.cmd 5 "ab" ababababab $ str_repeat.cmd 2 "Hello World" Hello WorldHello World |
$ str_repeat.cmd 3 * *** $ str_repeat.cmd 5 "ab" ababababab $ str_repeat.cmd 2 "Hello World" Hello WorldHello World
We enable the “enableDelayedExpansion” to allow variable substitution at runtime. And we use the for /L to loop for the given number of times.
