Assignment statements preceding shell function calls persist in the shell environment after the function returns, as if a POSIX special builtin command had been executed. - 35. The 'command' builtin does not prevent builtins that take + 34. The 'command' builtin does not prevent builtins that take assignment statements as arguments from expanding them as assignment statements; when not in POSIX mode, assignment builtins lose their assignment statement expansion properties when preceded by 'command'. - 36. The 'bg' builtin uses the required format to describe each job + 35. The 'bg' builtin uses the required format to describe each job placed in the background, which does not include an indication of whether the job is the current or previous job. - 37. The output of 'kill -l' prints all the signal names on a single + 36. The output of 'kill -l' prints all the signal names on a single line, separated by spaces, without the 'SIG' prefix. - 38. The 'kill' builtin does not accept signal names with a 'SIG' + 37. The 'kill' builtin does not accept signal names with a 'SIG' prefix. - 39. The 'export' and 'readonly' builtin commands display their output + 38. The 'export' and 'readonly' builtin commands display their output in the format required by POSIX. - 40. The 'trap' builtin displays signal names without the leading + 39. The 'trap' builtin displays signal names without the leading 'SIG'. - 41. The 'trap' builtin doesn't check the first argument for a possible + 40. The 'trap' builtin doesn't check the first argument for a possible signal specification and revert the signal handling to the original disposition if it is, unless that argument consists solely of digits and is a valid signal number. If users want to reset the handler for a given signal to the original disposition, they should use '-' as the first argument. - 42. The '.' and 'source' builtins do not search the current directory + 41. The '.' and 'source' builtins do not search the current directory for the filename argument if it is not found by searching 'PATH'. - 43. Enabling POSIX mode has the effect of setting the + 42. Enabling POSIX mode has the effect of setting the 'inherit_errexit' option, so subshells spawned to execute command substitutions inherit the value of the '-e' option from the parent shell. When the 'inherit_errexit' option is not enabled, Bash clears the '-e' option in such subshells. - 44. Enabling POSIX mode has the effect of setting the 'shift_verbose' + 43. Enabling POSIX mode has the effect of setting the 'shift_verbose' option, so numeric arguments to 'shift' that exceed the number of positional parameters will result in an error message. - 45. When the 'alias' builtin displays alias definitions, it does not + 44. When the 'alias' builtin displays alias definitions, it does not display them with a leading 'alias ' unless the '-p' option is supplied. - 46. When the 'set' builtin is invoked without options, it does not + 45. When the 'set' builtin is invoked without options, it does not display shell function names and definitions. - 47. When the 'set' builtin is invoked without options, it displays + 46. When the 'set' builtin is invoked without options, it displays variable values without quotes, unless they contain shell metacharacters, even if the result contains nonprinting characters. - 48. When the 'cd' builtin is invoked in LOGICAL mode, and the pathname + 47. When the 'cd' builtin is invoked in LOGICAL mode, and the pathname constructed from '$PWD' and the directory name supplied as an argument does not refer to an existing directory, 'cd' will fail instead of falling back to PHYSICAL mode. - 49. When the 'cd' builtin cannot change a directory because the length + 48. When the 'cd' builtin cannot change a directory because the length of the pathname constructed from '$PWD' and the directory name supplied as an argument exceeds PATH_MAX when all symbolic links are expanded, 'cd' will fail instead of attempting to use only the supplied directory name. - 50. The 'pwd' builtin verifies that the value it prints is the same as + 49. The 'pwd' builtin verifies that the value it prints is the same as the current directory, even if it is not asked to check the file system with the '-P' option. - 51. When listing the history, the 'fc' builtin does not include an + 50. When listing the history, the 'fc' builtin does not include an indication of whether or not a history entry has been modified. - 52. The default editor used by 'fc' is 'ed'. + 51. The default editor used by 'fc' is 'ed'. - 53. The 'type' and 'command' builtins will not report a non-executable + 52. The 'type' and 'command' builtins will not report a non-executable file as having been found, though the shell will attempt to execute such a file if it is the only so-named file found in '$PATH'. - 54. The 'vi' editing mode will invoke the 'vi' editor directly when + 53. The 'vi' editing mode will invoke the 'vi' editor directly when the 'v' command is run, instead of checking '$VISUAL' and '$EDITOR'. - 55. When the 'xpg_echo' option is enabled, Bash does not attempt to + 54. When the 'xpg_echo' option is enabled, Bash does not attempt to interpret any arguments to 'echo' as options. Each argument is displayed, after escape characters are converted. - 56. The 'ulimit' builtin uses a block size of 512 bytes for the '-c' + 55. The 'ulimit' builtin uses a block size of 512 bytes for the '-c' and '-f' options. - 57. The arrival of 'SIGCHLD' when a trap is set on 'SIGCHLD' does not + 56. The arrival of 'SIGCHLD' when a trap is set on 'SIGCHLD' does not interrupt the 'wait' builtin and cause it to return immediately. The trap command is run once for each child that exits. - 58. The 'read' builtin may be interrupted by a signal for which a trap + 57. The 'read' builtin may be interrupted by a signal for which a trap has been set. If Bash receives a trapped signal while executing 'read', the trap handler executes and 'read' returns an exit status greater than 128. - 59. Bash removes an exited background process's status from the list + 58. Bash removes an exited background process's status from the list of such statuses after the 'wait' builtin is used to obtain it. There is other POSIX behavior that Bash does not implement by default @@ -11846,60 +11844,60 @@ Node: Directory Stack Builtins273455 Node: Controlling the Prompt276423 Node: The Restricted Shell279344
