* sh: Fix $? in the first command of a 'for'.Jilles Tjoelker2012-01-221-1/+4
| | | | | | | | | In the first command of a 'for', $? should be the exit status of the last pipeline (command substitution in the word list or command before 'for'), not always 0. Notes: svn path=/head/; revision=230463

* Remove unused variables.Ed Schouten2012-01-171-96/+30
| | | | | | | | Simply annotate the function parameters with __unused, instead of adding the ve-variables. This makes the code build with GCC 4.7 and -Werror. Notes: svn path=/head/; revision=230287
* sh: Fix execution of multiple statements in a trap when evalskip is setJean-Sébastien Pédron2012-01-163-2/+34
| | | | | | | | | | | | | | Before this fix, only the first statement of the trap was executed if evalskip was set. This is for example the case when: o "-e" is set for this shell o a trap is set on EXIT o a function returns 1 and causes the script to abort Reviewed by: jilles MFC after: 2 weeks Notes: svn path=/head/; revision=230212
* sh: Fix some bugs with exit status from case containing ;&.Jilles Tjoelker2012-01-151-9/+24
| | | | | | | | | | | | | | | | Also, rework evalcase() to not evaluate any tree. Instead, return the NCLISTFALLTHRU node and handle it in evaltree(). Fixed bugs: * If a ;& list with non-zero exit status is followed by an empty ;; or final list, the exit status of the case command should be equal to the exit status of the ;& list, not 0. * An empty ;& case should not reset $?. Notes: svn path=/head/; revision=230161
* sh: Fix two bugs with case and exit status:Jilles Tjoelker2012-01-151-1/+3
| | | | | | | | | | * If no pattern is matched, POSIX says the exit status shall be 0 (even if there are command substitutions). * If a pattern is matched and there are no command substitutions, the first command should see the $? from before the case command, not always 0.

* Simplify df(1) by factoring out most of the common code:Dag-Erling Smørgrav2011-10-181-26/+27
| | | | | | | | | | | | | | | | | | | | | | | | - In the argc == 0 case, just populate the mount list as before, but do not calculate widths, update totals or print anything. - In the argv > 0 case, collect information about the requested file systems and store it in the mount list, but do not calculate widths, update totals or print anything. - In either case, once all the information has been collected, iterate once through the mount list to calculate widths and totals, then once more to print everything. This also fixes two bugs: firstly, column widths were not calculated correctly if more than one file system was specified on the command line; and secondly, file systems with MNT_IGNORE were included in the totals even if -a was not specified.

* Get rid of major/minor number distinction.Ed Schouten2011-09-285-45/+22
| | | | | | | | | | | | | | | | | | | | | | | | | As of FreeBSD 6, devices can only be opened through devfs. These device nodes don't have major and minor numbers anymore. The st_rdev field in struct stat is simply based a copy of st_ino. Simply display device numbers as hexadecimal, using "%#jx". This is allowed by POSIX, since it explicitly states things like the following (example taken from ls(1)): "If the file is a character special or block special file, the size of the file may be replaced with implementation-defined information associated with the device in question." This makes the output of these commands more compact. For example, ls(1) now uses approximately four columns less. While there, simplify the column length calculation from ls(1) by calling snprintf() with a NULL buffer. Don't be afraid; if needed one can still obtain individual major/minor numbers using stat(1).

* sh(1): Extend documentation about subshells.Jilles Tjoelker2011-07-101-8/+46
| | | | | | | | | | | | | | Because sh executes commands in subshell environments without forking in more and more cases (particularly from 8.0 on), it makes sense to describe subshell environments more precisely using ideas from POSIX, together with some FreeBSD-specific items. In particular, the hash and times builtins may not behave as if their state is copied for a subshell environment while leaving the parent shell environment unchanged.

* Make /bin/expr support 64bit numeric range and range checks by default,Stefan Eßer2011-07-092-140/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | again. This brings back the behaviour of expr in FreeBSD-4, which had been reverted due to an assumed incompatbility with POSIX.1 for FreeBSD-5. This issue has been discussed in the freebsd-standards list, and the consensus was, that POSIX.1 is in fact not violated by this extension, since it affects only cases of POSIX undefined behaviour (overflow of signed long). Other operating systems did upgrade their versions of expr to support 64bit range, after it had been initially brought to FreeBSD. They have used it for a decade without problems, meanwhile. The -e option is retained, but it will only select less strict checking of numeric parameters (leading white-space, leading "+" are allowed and skipped, an empty string is considered to represent 0 in numeric context.) The call of check_utility_compat() as a means of establishing backwards compatibility with FreeBSD-4 is considered obsolete, but preserved in this commit. It is expected to be removed in a later revision of this file. Reviewed by: bde, das, jilles MFC after: 2 month (those parts that do not violate POLA) Notes: svn path=/head/; revision=223881
