simple example: user:/$ find /garbage | wc -l find: '/garbage': no such file or directory 0 user:/$ echo $? 0 find fails, wc executes , $?=0 . rather abort, , $? set find 's status code. this seems work user:/$ find /garbage 2> /dev/null && if [ ! $? -eq 0 ]; exit $?; fi | wc -l user:/$ echo ? 3 but it's clunky , feels there's cleaner, more bashonic solution. taken man bash : the return status of pipeline exit status of last command, unless pipefail option enabled. if pipefail enabled, pipeline's return status value of last (right‐ most) command exit non-zero status, or 0 if commands exit successfully. if reserved word ! precedes pipeline, exit status of pipeline logical negation of exit status described above. shell waits commands in pipeline terminate before returning value. to set it: set -o pipefail

twitter bootstrap 3.1.0 comes rules waste horizontal space on wide screens. when remove them nothing seems break, breaking. know if break or why these included? thank you! @media (min-width: 768px) { .container { width: 750px; } } @media (min-width: 992px) { .container { width: 970px; } } @media (min-width: 1200px) { .container { width: 1170px; } } from why bootstrap 3 force container width sizes? , the official answer bootstrap folks: what boils down designing specific breakpoints easier (in mind) designing unlimited, unknown sizes. alternative mention isn't wrong or bad, different. i'd rather maintain tiers specific ranges bootstrap's grid system makes more feasible method. there shouldn't breaking if find other spacing issues continue digging, might reason.
