DP(8) [nmh-1.5] DP(8)NAMEdp - parse dates 822-styleSYNOPSIS/usr/lib/mh/dp [-form formatfile] [-format string] [-width columns] [-version] [-help] dates ...DESCRIPTIONDp 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 profilePROFILE COMPONENTSNoneSEE ALSOap(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 terminalCONTEXTNoneBUGSThe 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. MH.6.8 11 June 2012 DP(8)
