* Use -F instead of -f in tail(1) examplesMateusz Piotrowski2020-03-221-2/+2
| | | | | | | | | | | | | | | There is an example in tail(1) manual page explaining how to use tail(1) to track the contents of /var/log/messages. The example uses the -f flag to follow the file. The problem with the -f flag is that it cannot handle the situation where /var/log/messages is rotated. Hence, use -F instead in the example.

* Fix tail -f in capability mode.Mark Johnston2019-12-061-5/+8
| | | | | | | | | | | | | | We were not adding CAP_EVENT to input file capabilities, so kevent() always failed with ENOTCAPABLE. tail implements a fallback mode to poll the file in this case, so the failure was not apparent.

* tail: fix the checks if the file was rotatedMariusz Zaborski2019-06-096-11/+31
| | | | | | | | | | | | | | | | | The freopen(3) was replaced with fileargs_open(3) and fclose(3). In the following function, we skip if the stream is standard in, so it is safe to do so. This also requires us to change the logic first to open the file and then check its status. The stat(2) is disallowed in capability mode. This commit unbrakes the -F option. The bug was introduced in the r348708. Reported by: pho Tested by: pho Notes: svn path=/head/; revision=348842

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-206-0/+12
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025

| | | | | | | | | | | | | | | | In the case where write(2) does not return -1, it does not initialize errno. This can happen when a broken pipe causes a short write.

So the aborted test is left disabled, in case someone would like to run it manually or fix it.

This behaviour is consistent with the GNU version of tail but without the verbiage that goes with the GNU version. This change also fixes error messages accompanying -f and -F.
