* Improve the change made in the previous commit.ed2010-03-111-2/+1
| | | | | doshell() never returns, so there is no need to see whether we are the parent process.
* Make script(1) a little less broken.ed2010-03-111-0/+2
| | | | | | | | | Close the file descriptor to the TTY. There is no reason why the parent process should keep track of the descriptor. This ensures that the application inside properly drains the TTY during exit(2). Reported by: alfred MFC after: 2 weeks
* Remove a warning by adding extra parentheses.ed2010-01-021-1/+1
| | | | | GCC generates warnings when using "if (foo = bar)". In this case its use is valid.
* Attempt #2 to fix script(1) if the standard input is closed: If wecperciva2004-02-151-1/+3
| | | | | | | | | | | | | | | | read EOF from STDIN_FILENO, write zero bytes into the pseudo-terminal; this is interpreted as an EOF by the program being scripted. I've tested this with two non-interactive scripts: # echo 5 | script foo sh -c 'read x; sleep $x; echo bar' # echo bar | xargs script foo echo and one interactive program: # script foo more /etc/passwd and everything seems to work properly...

* Back out part of 1.21, since it breaks `script interactive-program`. Thiscperciva2004-01-271-2/+1
| | | | | | | | | re-breaks non-interactive portupgrade (or at least old versions of portupgrade); I'll see if I can put together a solution which avoids breaking anything later. Approved by: rwatson (mentor) Noticed by: Stefan Farfeleder, Joshua Goodall
* Fix SYNOPSIS of manual page, clustering no-arg options correctly.sheldonh2004-01-221-1/+1
| | | | Sync usage with manpage.
* Two fixes for script(1):cperciva2004-01-221-11/+22
| | | | | | | | | | | | | 1. Don't do tty stuff to stdin if stdin isn't a tty. 2. When running in non-interactive mode, don't select(2) on the standard input. This un-breaks non-interactive portupgrade. PR: bin/59036 [1] PR: bin/56166, bin/57414, ports/57415, ports/60534 [2] MFC after: 7 days Approved by: rwatson (mentor)
* ANSIify function definitions.dwmalone2002-09-041-10/+6
| | | | | | | | | Add some constness to avoid some warnings. Remove use register keyword. Deal with missing/unneeded extern/prototypes. Some minor type changes/casts to avoid warnings. Reviewed by: md5
* Use POSIX macros for wait(2)-style status information instead of themike2002-06-031-3/+3
| | | | | deprecated 4.2/4.3BSD wait union. Fix some nearby pid_t/int confusion.

* Warns cleanups. Add FreeBSD ID.dwmalone2001-12-031-2/+2

* Use STD{ERR,IN,OUT}_FILENO instead of their numeric values. Thesheldonh2001-07-261-1/+1
| | | | | | | definitions are more readable, and it's possible that they're more portable to pathalogical platforms. Submitted by: David Hill <david@phobia.ms>

* Pass as argv[0] the name of the shell executed instead of "sh".sheldonh1999-08-111-2/+2

* Fix the following bugs:des1998-09-191-19/+27
| | | | | | | | | | | | | | | | | - if a command was specified and script(1) failed to execute it, it would print the name of your shell in the error message instead of that of the command that failed. - since finish() was installed as a SIGCHLD handler, it would often run before the main loop had had time to process the last few bytes of output. This resulted in very strange truncated error messages. - script(1) would almost always return with an exit status of 0, even if the command returned a non-zero exit status. This broke my 'build world, install it and rebuild the kernel' scripts because 'make installworld' would run even if 'make buildworld' had failed.
* Rewrite script as a select loop rather than as a twin reader/write process.peter1998-03-081-72/+78
| | | | | This allows simple logging of keys sent to a session (turned on with -k). Also allow specifying the script file flush interval.
* Fix typo while copying patch from the 2.2 system that it came frompeter1997-12-301-3/+3
| | | | Use execvp rather than execv so that full paths are not needed.
* script(1) has annoyed me with it's inflexable command argument parsingpeter1997-12-291-13/+27
| | | | | since I first saw it. I finally needed to pass arguments through to the spawned command badly enough (and urgently) that I threw this together.
* Add usage(). Use err(3) instead of local redefinition.charnier1997-08-081-39/+21

* compare return value from getopt against -1 rather than EOF, per the finalimp1997-03-291-1/+1

* Don't use __dead or __pure in user code. They were obfuscationsbde1996-09-141-7/+7
| | | | | | for gcc >= 2.5 and no-ops for gcc >= 2.6. Converted to use __dead2 or __pure2 where it wasn't already done, except in math.h where use of __pure was mostly wrong.
