vis — display
non-printable characters in a visual format
vis is a filter for converting
non-printable characters into a visual representation. It differs from
cat -v in that the form can be unique and
invertible. By default, all non-printing characters except space, tab, and
newline are encoded, as are any meta-characters (eighth bit set). A detailed
description of the various visual formats is given in
The options are as follows:
visto fold output lines to foldwidth columns, like fold(1), except that a hidden newline sequence is used, (which is removed when inverting the file back to its original form with unvis(1)). If the last character in the encoded file does not end in a newline, a hidden newline sequence is appended to the output. This makes the output usable with various editors and other utilities which typically don't work with partial lines.
-F, except output is always folded to 80 columns.
\$’, followed by the newline.
-Fis selected. When combined with the
visbecomes like an invertible version of the fold(1) utility. That is, the output can be unfolded by running the output through unvis(1).
