$ echo '$x'
$x
$ echo "$x"

$But I found this block a bit bewildering:$ echo $x'

$I'm wondering why substitution wasn't performed on the $x, since it was unquoted (as far as I can tell).... (5 Replies)

dp
DP(8) [nmh-1.5] DP(8)NAME
dp - parse dates 822-style
SYNOPSIS
/usr/lib/mh/dp [-form formatfile] [-format string] [-width columns] [-version] [-help] dates ...
DESCRIPTION
Dp is a program that parses dates according to the ARPA Internet standard. It also understands many non-standard formats, such as those
produced by TOPS-20 sites and some UNIX sites using ctime(3). It is useful for seeing how nmh will interpret a date.
The dp program treats each argument as a single date, and prints the date out in the official 822-format. Hence, it is usually best to
enclose each argument in quotes for the shell.
To override the output format used by dp, the -format string or -format file switches are used. This permits individual fields of the
address to be extracted with ease. The string is simply a format string and the file is simply a format file. See mh-format(5) for the
details.
Here is the default format string used by dp:
%<(nodate{text})error: %{text}%|%(putstr(pretty{text}))%>
which says that if an error was detected, print the error, a `:', and the date in error. Otherwise, output the 822-proper format of the
date.
FILES
$HOME/.mh_profile The user profile
PROFILE COMPONENTS
None
SEE ALSO ap(8), Standard for the Format of ARPA Internet Text Messages (RFC-822)
DEFAULTS
`-format' default as described above
`-width' default to the width of the terminal
CONTEXT
None
BUGS
The argument to the -format switch must be interpreted as a single token by the shell that invokes dp. Therefore, one must usually place
the argument to this switch inside quotes.
