KSH(I)
Line feed and print current line. Has effect
only in control mode.
(New line) Execute the current line, regardless
of mode.
(Return) Execute the current line, regardless of
mode.
# Equivalent to I#< cr > . Useful for causing
the current line to be inserted in the history
without being executed.
Special Commands.
The following commands are executed in the shell process.
Input/Output redirection is permitted. File descriptor 1 is the
default output location. Parameter assignment lists preceding the
command do not remain in effect when the command completes
unless noted.
: [ arg ... ]
Parameter assignments remain in effect after the command
completes. The command only expands parameters.
A zero exit code is returned .
• file [ arg ... ]
Parameter assignments remain in effect after the command
completes. Read and execute commands from file
and return. The commands are executed in the current
Shell environment. The search path specified by PATH �
is used to find the directory containing file . If any argu- ·�
ments arg are given, they become the positional parameters.
Otherwise the positional parameters are unchanged.
alias [ -tx ] [ name[ =value ] ... ]
Alias with no arguments prints the list of aliases in the
form name =value on standard output. An alias is
defined for each name whose value is given. A trailing
space in value causes the next word to be checked for alias
substitution. The -t flag is used to set and list tracked
aliases. The value of a tracked alias is the full pathname
corresponding to the given name . The value becomes
undefined when the value of PATH is reset but the
aliases remain tracked. Without the -t flag, for each
name in the argument list for which no value is given, the
name and value of the alias is printed. The -x flag is
used to set or print exported aliases. An exported alias is
defined across sub-shell environments. Alias returns true
unless a name is given for which no alias has been defined.
bg [%job ]
This command is only built-in on systems that support
job control. Puts the specified job into the background.
The current job is put in the background if job is not
specified.
break [ n ]
Exit from the enclosing for , while, until, or select loop,
