In a system script I find this snippet nodevs=$(< /proc/filesystems fgrep rootfs)
and don't understand the syntax. According to the bash man page, $(< file) is shorthand for $(cat file). But then the above should read nodevs=$(< /proc/filesystems | fgrep rootfs) However, the latter leaves $nodevs empty whereas the former puts the stuff that fgrep processes into nodevs as it should. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
