RETURNS previously conflated fish's $status exit code with genuine stdout/printed output, e.g. rm listing "0/1" as if they were print values rather than exit codes. Rename RETURNS to EXIT STATUS across all 83 documented functions, and reintroduce RETURNS as a distinct label reserved for the 15 functions that actually print to stdout. Update build-manual.py's ENTRY_HEADS to render Exit Status before Returns, manualtools.py's SECTIONS constant, and AGENTS.md's label order and label-usage guidance to match. Add two verify-manual.py regression tests: EXIT STATUS bodies must never contain stray stdout/printed language, and Returns: must always render after Exit Status: when both are present. Regenerate docs/fish-config.md.

# SYNOPSIS
|
|
# fc [command_prefix]
|
|
#
|
|
# DESCRIPTION
|
|
# Edits the last shell command -- or the most recent one matching a
|
|
# prefix -- in $EDITOR, then executes the result. Bash-style fc
|
|
# behaviour. Falls back to vi when $EDITOR is unset, and aborts without
|
|
# executing if the buffer is left empty.
|
|
#
|
|
# ARGUMENTS
|
|
# command_prefix Search history for the newest command matching this
|
|
#
|
|
# EXIT STATUS
|
|
# The edited command's exit status, or a message when history lookup
|
|
# found nothing.
|
|
#
|
|
# EXAMPLE
|
|
# fc
|
|
# fc git
|
|
function fc --description 'Edit and execute the last command (Bash-style fc)'
|
|
set -l tmpfile (mktemp /tmp/fish_fc.XXXXXX).fish

# Search for a specific previous command
|
|
builtin history search --max=1 "$argv" | sed 's/^[0-9-]* [0-9:]* //' >$tmpfile
|
|
else
|
|
# Grab the last 2 commands, then take the 2nd one (the one before 'fc')
|
|
# This avoids the --skip flag entirely
|
|
builtin history --max=2 | sed 's/^[0-9-]* [0-9:]* //' | sed -n 2p >$tmpfile
