minus-squareBadabinski@kbin.earthlinkfedilinkarrow-up2·19 hours agoI was waiting for someone to come along with this response lmao I’m terrible at remembering shell string operation syntax, but this is the ultimate answer.
minus-squaresik0fewl@lemmy.calinkfedilinkarrow-up2arrow-down1·17 hours agoDefinitely not the ultimate, since it’s not POSIX, but still a nice tidbit.
minus-squareBadabinski@kbin.earthlinkfedilinkarrow-up3·17 hours agoIdk, writing POSIX-compliant shell is so miserable that I avoid doing it when I can. You can use Bash on BSD and all other unixes, so it’s still a relatively portable solution.
minus-squaresik0fewl@lemmy.calinkfedilinkarrow-up2arrow-down1·17 hours agoTrue enough, but it’s pretty much the same to use sed, unless you need those milliseconds of performance boost.
minus-squarea_non_monotonic_function@lemmy.worldlinkfedilinkarrow-up2arrow-down1·19 hours agoI think I find the pipe faster to parse.
