The input and output arguments are mandatory, but may be specified as ‘-’ for standard input or output. Reseq doesn’t let output default to standard output because, since it generates raw terminal codes, it is uncommon (and potentially unsafe) to send this directly to the terminal. The exception is when the --replay argument has been specified, which is only useful when output is going to the terminal; in that event, the output argument is optional.
Print usage information on standard output and exit successfully.
Print the version number and licensing information of
standard output and then exit successfully.
Honor delay lines in the input, pausing the specified amount of time
before continuing to process the next line. This is useful for
producing behavior equivalent to that of the
scriptreplay command (from
but using a Teseq output file as input, rather than a raw typescript
Only takes effect if ‘--replay’ is also specified. In addition to
honoring delay lines, also honors user-inserted “halt” lines (those
beginning with ‘@@@’) in the input. These lines cause
reseq to halt processing until the user presses a key.
This halting action is not accompanied by any sort of indication that
reseq is awaiting user action; it is up to the user to
ensure that the input script to
reseq has included some sort
of appropriate indication.
When ‘--halts’ is in effect,
reseq will turn off
terminal echoing (so the user’s keypress to continue the script is not
shown), and switches the terminal over to unbuffered I/O, so that
keypresses can be read as soon as they are typed.
Produce timing information from delay lines, in the format generated
script -t. This can be used to regenerate
typescript and timing files that were fed as the input to
teseq -t timings. Note that the result will differ slightly
from the output from
script -t, in that the first delay will be
zeroed out (
teseq always throws out the first delay value,
whose value from script is an arbitrary value between 0 and 1), and
the last delay line will include all the remaining characters
script’s timings don’t count the final timestamp line).
reseq command essentially does the reverse of
teseq. If you feed it the output from
will generate the corresponding escape sequences—that is, it will
generate the same content that was fed to
teseq to produce
that output. The shell command
$ teseq foo | reseq - -
is roughly equivalent to
$ cat foo
reseq command is written in
which is compiled from C-language sources, and so requires a Perl
interpreter to be present in order to function.
Of the various types of lines output by the
reseq only understands four;
|Hello, there|. |Here are|- -|some wrapped|- -|lines|.
. CR/^M LF/^J . CR LF
: Esc [ 31 ; 3 m
And, of course, delay lines:
