\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.
\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.
