\section commandline commandline - set or get the current command line buffer
|

|

\subsection commandline-synopsis Synopsis
|
|
<tt>commandline [OPTIONS] [CMD]</tt>
|
|
|
|
\subsection commandline-description Description
|
|
|
|
\c commandline can be used to set or get the current contents of the command
|
|
line buffer.
|
|
|
|
With no parameters, \c commandline returns the current value of the command
|
|
line.
|
|
|
|
With \c CMD specified, the command line buffer is erased and replaced with
|
|
the contents of \c CMD.
|
|
|
|
The following options are available:
|
|
|
|
- \c -C or \c --cursor set or get the current cursor position, not
|
|
the contents of the buffer. If no argument is given, the current
|
|
cursor position is printed, otherwise the argument is interpreted
|
|
as the new cursor position.
|
|
- \c -f or \c --function inject readline functions into the
|
|
reader. This option cannot be combined with any other option. It
|
|
will cause any additional arguments to be interpreted as readline
|
|
functions, and these functions will be injected into the reader, so
|
|
that they will be returned to the reader before any additional
|
|
actual key presses are read.
|
|
|
|
The following options change the way \c commandline updates the
|
|
command line buffer:
|
|
|
|
- \c -a or \c --append do not remove the current commandline, append
|
|
the specified string at the end of it
|
|
- \c -i or \c --insert do not remove the current commandline, insert
|
|
the specified string at the current cursor position
|
|
- \c -r or \c --replace remove the current commandline and replace it
|
|
with the specified string (default)
|
|
|
|
The following options change what part of the commandline is printed
|
|
or updated:
|
|
|
|
- \c -b or \c --current-buffer select the entire buffer (default)
|
|
- \c -j or \c --current-job select the current job
|
|
- \c -p or \c --current-process select the current process
|
|
- \c -t or \c --current-token select the current token.
|
|
|
|
The following options change the way \c commandline prints the current
|
|
commandline buffer:
|
|
|
|
- \c -c or \c --cut-at-cursor only print selection up until the
|
|
current cursor position
|
|
- \c -o or \c --tokenize tokenize the selection and print one string-type token per line
|
|
|
|
|
|
If \c commandline is called during a call to complete a given string
|
|
using <code>complete -C STRING</code>, \c commandline will consider the
|
|
specified string to be the current contents of the command line.
|
|
|
|
The following options output metadata about the commandline state:
|
|
|
|
- \c -L or \c --line print the line that the cursor is on, with the topmost
|
|
line starting at 1
|
|
- \c -S or \c --search-mode evaluates to true if the commandline is performing
|
|
a history search
|
|
- \c -P or \c --paging-mode evaluates to true if the commandline is showing
|
|
pager contents, such as tab completions
|
|
|
|
|
|
\subsection commandline-example Example
|
|
|
|
<tt>commandline -j $history[3]</tt> replaces the job under the cursor with the
|
|
third item from the command line history.
