https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264846 Bug ID: 264846 Summary: xargs should terminate if line replacement cannot be constructed Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: misc Assignee: bugs@FreeBSD.org Reporter: thj@FreeBSD.org Flags: exp-run? Created attachment 234885 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D234885&action= =3Dedit cause xargs to error if line cannot be constructed https://reviews.freebsd.org/D35574 If the line with replacement cannot be constructed xargs should terminate as documented in the man page: -I replstr=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 Execute utility for each input line, replacing one or more=20=20=20= =20=20=20=20 occurrences of replstr in up to replacements (or 5 if no -R flag=20 is specified) arguments to utility with the entire line of input. The resulting arguments, after replacement is done, will not be=20= =20 allowed to grow beyond replsize (or 255 if no -S flag is=20=20=20= =20=20=20=20=20=20 specified) bytes; this is implemented by concatenating as much of the argument containing replstr as possible, to the constructed=20= =20 arguments to utility, up to replsize bytes. The size limit does=20 not apply to arguments to utility which do not contain replstr,=20= =20 and furthermore, no replacement will be done on utility itself.=20= =20 Implies -x. Currently, xargs continues and lines that cannot accommodate the replacement get as much of the replstr as will fit in the string. Instead xargs should erro= r, include an error when we do. We encounter this error, but gnu/xargs doesn't because they have a much lar= ger limit for created outputs (~10000 lines). --=20 You are receiving this mail because: You are the assignee for the bug.=
