fmt(1) General Commands Manual fmt(1)
NAME
fmt - Formats mail messages prior to sending
SYNOPSIS
fmt [-width] file...
DESCRIPTION
The fmt command reads the input file or files, or standard input if no files are specified, and writes to standard output a version of the
input with lines of a length as close as possible to width columns. (Because fmt is internationalized software, the number of display col-
umns is not necessarily equivalent to the number of bytes.)
The fmt command both joins and splits lines to achieve the desired width, but words are never joined or split; spaces are always preserved,
and lines are split at spaces only. In effect, fmt ignores newline characters in the input and wraps words to make lines a close as possi-
ble to width columns, resulting in individual lines of varying length but a consistent (new) text width overall. Because blank lines are
always preserved, fmt does not merge paragraphs separated by blank lines.
If you specify more than one file, the files are concatenated as input to fmt. If you do not specify -width, the default line length is 72
columns. Spacing at the beginning of input lines is always preserved in the output.
The fmt command is generally used to format mail messages to improve their appearance before they are sent. It may also be useful, how-
ever, for other simple formatting tasks. For example, when you are using vi, you can use the command :%!fmt -60 to reformat your text so
that all lines are approximately 60 columns long.
NOTES
The fmt command is a fast, simple formatting program. Standard text editing programs are more appropriate than fmt for complex formatting
operations. Do not use the fmt command if the message contains embedded messages or preformatted information from other files. This com-
mand formats the heading information in embedded messages and may change the format of preformatted information.
EXAMPLES
file1 contains these lines:
Australia is an island-continent, home to many very interesting plants and animals.
To reformat this text to a narrower width, enter: fmt -30 file1
This results in the following, displayed on your screen: Australia is an island-continent, home to many very interesting plants and
animals.
To make file1 wider, enter: fmt -60 file1
This results in: Australia is an island-continent, home to many very interesting plants and animals. To format a message you have
created with the mailx editor, at the left margin enter: ~|fmt
After you enter the command, your message is formatted, in this case to the default line length of 72 columns, and the word continue
is displayed to indicate that you can enter more information or send your message.
