* colcrt: reimplementationSami Kerola2016-02-021-243/+176Star
| | | | | | | | | | This implementation aims to be easier to read, more robust dealing all sorts of unexpected inputs, and possibly even more correct. The correctness refers to last line handling this implementation does differently than the previous. With the previous last line that ended to EOF without \n was not printed.

* build-sys: remove libtermcap supportSami Kerola2016-01-262-91/+23Star
| | | | | | | | | | It is unlikely anyone is going to build this project on system where libtermcap is available. Fedora project obsoleted libtermcap 2007-12-12 in favour of ncurses. Debian made same move 2005.

* lib/tty: Pass default width to get_terminal_width()Boris Egorov2016-01-061-3/+1Star
| | | | | | | | | | Almost any code calling get_terminal_width() checks returned width for non-positive values and sets it to some default value (say, 80). So, let's pass this default value directly to the function. [kzak@redhat.com: - get_terminal_width() refactoring] Signed-off-by: Karel Zak <kzak@redhat.com>

* tailf: deprecatedRuediger Meier2015-03-162-4/+16
| | | | | | | | | | | | We want to remove it in 2 years, March 2017. See discussion "tailf, really needed?" http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/10967 [kzak@redhat.com: - move warning to usage()] Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl> Signed-off-by: Karel Zak <kzak@redhat.com>
* tailf: use size_t and fwrite()Karel Zak2015-03-051-18/+14Star
| | | | | | | Let's use size_t for number of output lines and use fwrite() rather than while() { putchar() }; Signed-off-by: Karel Zak <kzak@redhat.com>
* tailf: ensure file argument really is a fileSami Kerola2015-03-051-1/+2
| | | | | | | | | | The tailf(1) never worked very well with block or character devices, sockets, fifos and such. Now after mmap() is used to find last lines even the little command used to work for example pipes is broken, so test the tailf is asked to follow a file and when not fail. That said symlinks are OK, as long they point to a file. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* tailf: do not allow minus signed last lines argumentSami Kerola2015-03-051-11/+13
| | | | | | | | | | | Before mmap() the command behavior was not completely correct, as demonstrated below, and after the mmap() it tried to print some eighteen quintillion lines. $ tailf -n-1 x tailf: cannot allocate 18446744073709543424 bytes: Cannot allocate memory Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* tailf: count last lines correctly at initial print outSami Kerola2015-03-051-41/+36Star
| | | | | | | | | When last lines happen to be greater than string buffer size for fgets() the number of printed lines resulted to too few. To avoid miscounts due insufficient buffer size use mmap() to map the whole file and rewind until requested number of new lines is found. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* lib/colors: use libtinfo to check terminal capabilityKarel Zak2015-02-271-1/+1
| | | | | | | | | | | | | | | The current implementation assumes that all terminals supports colors and users are forcet to use terminal-colors.d/ to disable colors for some terminals. This patch checks for maximal supported colors for the current terminal and colors are automatically disabled for terminals like vt100. The patch moves lib/colors.c from libcommon.la to libtcolors.la to avoid collisions with another utils. Signed-off-by: Karel Zak <kzak@redhat.com>

* textual: grammarize and harmonize the stat error messageBenno Schulenberg2015-02-022-3/+3
| | | | | | | | | The message "stat failed %s" seems to say that stat() failed to do something, or failed to pass a test, but of course it means that the statting of something failed. So say so. Also make two very similar messages equal to this one. Signed-off-by: Benno Schulenberg <bensberg@justemail.net>
* more: fix repeat search crashSami Kerola2015-01-281-0/+3
| | | | | | | | | Repeating a search for a pattern that did not found made more(1) to crash. To reproduce 'more /etc/services' and search for 'doom'; you will find a service in port 666 - pressing '.' after that result used to cause core dump. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
