From: Luke Shumaker <lukeshu@parabola.nu> This is similar to common C #ifdef guards. I was tempted to wrap the entire thing in the if/fi, rather than use 'return' to bail early. However, that means it won't execute anything until after it reaches 'fi'. And if `shopt -s extglob` isn't executed before parsing, then it will syntax-error on the extended globs. One solution would have been to move `shopt -s extglob` up above the include-guard. But the committed solution is all-around simpler. --- lib/common.sh | 3 +++ 1 file changed, 3 insertions(+)
