I historically on occasion have done something like: # grep -rI ... /
in order to find all instances of a text, including in build trees and such. I now find that I need to do something more like (using a more specific example): # grep -rI --exclude-dir /dev '#define.*__FreeBSD_version' otherwise the grep ends up reading from the tty and waits for it. Top shows, for example, 13470 root 22 0 12848Ki 2692Ki ttyin 11 0:00 0.00% grep -rI #define.*__FreeBSD_version / Is this expected? Should I have always been using "--exclude-dir /dev"? What lead to the behavior change? (FYI: The activity is normally as root.) I'll note that I also got a couple of other messages first: grep: /dev/log: Operation not supported grep: /dev/reroot/reroot: Operation not supported by device I do not remember getting these in the past. The issue happens with or without the -I part of the grep command. The context for the above is based on main 3acea07c1873 , or, in more detail, # ~/fbsd-based-on-what-freebsd-main.sh merge-base: 3acea07c1873b1e4042f4a4fa8668745ee59f15b merge-base: CommitDate: 2021-02-08 19:15:21 +0000 c1845d00f818 (HEAD -> mm-src) mm-src snapshot for mm's patched build in git context. 3acea07c1873 (pure-src) Restore the augmented strlen commentary FreeBSD FBSDFHUGE 14.0-CURRENT FreeBSD 14.0-CURRENT mm-src-n244686-c1845d00f818 GENERIC-NODBG amd64 amd64 1400004 1400004 === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
