file as having been found, though the shell will attempt to execute
such a file if it is the only so-named file found in '$PATH'.
51. The 'vi' editing mode will invoke the 'vi' editor directly when
52. The 'vi' editing mode will invoke the 'vi' editor directly when
the 'v' command is run, instead of checking '$VISUAL' and
'$EDITOR'.
52. When the 'xpg_echo' option is enabled, Bash does not attempt to
53. When the 'xpg_echo' option is enabled, Bash does not attempt to
interpret any arguments to 'echo' as options. Each argument is
displayed, after escape characters are converted.
53. The 'ulimit' builtin uses a block size of 512 bytes for the '-c'
54. The 'ulimit' builtin uses a block size of 512 bytes for the '-c'
and '-f' options.
54. The arrival of 'SIGCHLD' when a trap is set on 'SIGCHLD' does not

interrupt the 'wait' builtin and cause it to return immediately.
The trap command is run once for each child that exits.

56. The 'read' builtin may be interrupted by a signal for which a trap
has been set. If Bash receives a trapped signal while executing
'read', the trap handler executes and 'read' returns an exit status
greater than 128.
56. Bash removes an exited background process's status from the list

of such statuses after the 'wait' builtin is used to obtain it.
