https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235589 Bug ID: 235589 Summary: sh(1): LINENO is always 0 in shell arithmetic Product: Base System Version: 12.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: mcdutchie@hotmail.com In sh(1), the LINENO variable (currently executed line number) is always zero when it is read as part of a shell arithmetic expression. For instance: $ echo $LINENO $((LINENO)) $(($LINENO)) 108 0 108 Expected: 3 times "108" (or whatever the current line number is) Note that $(($LINENO)) does work because it expands LINENO as a normal shell expansion before invoking the arithmetic subsystem. However, $((LINENO)) should be equivalent as it is for all other variables. Another manifestation of the bug is: $ set -u $ echo $((LINENO)) -sh: arithmetic expression: variable not set: "LINENO" -- You are receiving this mail because: You are the assignee for the bug.help
