-b, --break-chars list_of_charactersConsider the specified characters word-breaking.help + man
-c, --complete-filenamesComplete filenames (filename completion is always case-sensitive, even with the -i option).help + man
-C, --command-name command_name|NUse command_name instead of command to determine the names of history and completion files, and to evaluate $if command_name conditionals in $INPUTRC.help + man
-D, --history-no-dupes nHow aggressively to weed out duplicate entries from the input history.help + man
-e, --extra-char-after-completion charBy default, rlwrap appends a space after any inserted completion text.help + man
-f, --file fileSplit file into words (using the default word-breaking characters, or those specified by a preceding --break-chars option), and add them to the completion word list.help + man
-g, --forget-matching regexpForget (i.e. never put into the history list) input lines that match the POSIX 1003.2 regular expression regexp.help + man
-h, --helpPrint a short help message.help + man
-H, --history-filename fileRead command history from file (and write it back there if --histsize >= 0)help + man
-i, --case-insensitiveIgnore case when completing (filename completion remains case-sensitive).help + man
-I, --pass-sigint-as-sigtermSend a TERM signal to command when an INT is received (e.g. when you press CTRL-C).help + man
-l, --logfile fileWhen in readline mode, append command's output (including echo'ed user input) to file (creating file when it doesn't exist).help + man
-m newline--multi-line[=newline substitute]help
-M, --multi-line-ext .extCall multi-line-editor on temporary files with filename extension .ext (useful for e.g. automatic syntax colouring)help + man
-n, --no-warningsDon't print warnings.help + man
-N, --no-childrenWhen rlwrap is invoked with the --always-readline option, editors and pagers that are called by the client will be pretty unusable, as they will see your keypresses only if you press ENTER.help + man
-o, --one-shotSend an EOF to command after accepting the first line of inputhelp + man
-O, --only-cook regexpOnly ever "cook" prompts that match regexp, which can be preceded by '!', meaning that all matching candidate prompts will be cooked immediately ("confident mode").help + man
-p colour--prompt-colour[=colour]help
-P, --pre-given textStart rlwrap with text in its edit buffer (this will automatically set the --always-readline option).help + man
-q, --quote-characters list_of_charactersAssume that the given characters act as quotes when matching parentheses.help + man
-r, --rememberPut all words seen on in- and output on the completion list.help + man
-R, --reniceMake rlwrap nicer than command (cf nice (1)).help + man
-s, --histsize NLimit the history list to N entries, truncating the history file (default: 300).help + man
-S, --substitute-prompt promptSubstitute the specified prompt for command's own prompt.help + man
-t, --set-terminal-name name<name> --set-term-name=<name>help + man
-U, --mirror-arguments(linux only) Keep track of command's arguments as seen by the ps (1) command, and mirror them in rlwrap's own arguments This can be useful for commands that overwrite command-line password arguments…help + man
-v, --versionPrint rlwrap version.help + man
-w, --wait-before-prompt timeoutIn order to determine if command's last output is a prompt, rlwrap waits timeout milliseconds after receiving it.help + man
-W, --pollingWake up every timeout millisecs, where timeout is the same as for the -w (--wait-before-prompt) option, 40 ms by default.help + man
-X, --skip_setcttyDon't create a new session for command: command will inherit the controlling terminal of the process that invokes rlwrap.help + man
-z, --filter filter<filter command> --filter=<filter command> ('rlwrap -z listing' writes a list of installed filters)help + man
-E, --always-echoBy default, rlwrap avoids displaying passwords by echoing '' whenever the client clears the ECHO flag on its input. (in the manual page but not in --help)man
