![]() ![]() Terminates a login shell and invokes login (1). ![]() Resource is one of: cputime, maximum CPU seconds per process filesize, largest single file allowed datasize, maximum data size (including stack) for the process stacksize, maximum stack size for the process coredump, maximum size of a core dump and descriptors, maximum value for a file descriptor. Only the superuser may raise the hard limits. Hard limits impose a ceiling on the values of the current limits. Uses hard limits instead of the current limits. If max “use is omitted, print the current limit if resource is omitted, display all limits. Limit the consumption by the current process or any process it spawns, each not to exceed max “use on the specified resource. If the signal being sent is TERM (terminate) or HUP (hangup), then the job or process is sent a CONT (continue) signal as well. Typing kill does not send a signal to the current job. Signals are given either by number or name. Sends the TERM (terminate) signal, by default or by the signal specified, to the specified ID, the job indicated, or the current job. “Lists IDs in addition to the normal information. See "Conditional Constructs and Flow Control" on page 535. This is used to produce files suitable for sourcing using the “h option to source. Reverses the order of the printout to be most recent first rather than oldest first.ĭisplays the history list without leading numbers. An exec is attempted for each component of the path where the hash function indicates a possible hit, and in each component that does not begin with a backslash.ĭisplays the history list if n is given, display only the n most recent events. Prints a statistics line indicating how effective the internal hash table has been at locating commands (and avoiding execs ). Words are delimited by null characters in the output. Like echo, but no escapes ( \ ) are recognized. īrings the current or specified job into the foreground. This is usually used to execute commands generated as the result of command or variable substitution, as parsing occurs before these substitutions (e.g., eval 'tset -s options' ).Įxecutes command in place of the current shell, which terminates.Įxits the shell, either with the value of the status variable or with the value specified by expr. Runs command as standard input to the shell and executes the resulting commands. The output is terminated with a newline unless the “n option is used. ![]() Writes the words in list to the shell's standard output, separated by space characters. With the “l argument, produces an unabbreviated printout use of the ~ notation is suppressed. Prints the directory stack, most recent to the left the first directory shown is the current directory. The default should come after all case labels. ![]() Labels the default case in a switch statement. Ĭontinues execution of the nearest enclosing while or foreach. If no argument is given, change to the home directory of the user. Ĭhanges the shell's working directory to dir. īreaks from a switch, resuming after the endsw. Runs the current or specified jobs in the background.īreaks out of the innermost foreach or while loop. Interprets null command, but performs no action. C and TC Shell Built-In Commands and Their Meanings For an extended list of TC shell only built-in commands, see Table 9.25 on page 504. See Table 10.11 for a list of built-in commands that apply to both the C and TC shells. If a built-in command occurs as any component of a pipeline except the last, it is executed in a subshell. Rather than residing on disk like UNIX/Linux commands, built-in commands are part of the C/TC shell's internal code and are executed from within the shell. ![]()
