| 26 | .SH DESCRIPTION |
|---|
| 27 | The |
|---|
| 28 | .I from |
|---|
| 29 | program prints out the mail header lines in your incoming mail |
|---|
| 30 | to show you who your mail is from. It does this by checking for mail |
|---|
| 31 | on a POP server and then looking for mail in the local spool |
|---|
| 32 | directory. This command does not retrieve the mail from the post |
|---|
| 33 | office or the spool directory. |
|---|
| 34 | |
|---|
| 35 | If no mail is waiting, |
|---|
| 36 | .I from |
|---|
| 37 | is silent unless one of |
|---|
| 38 | .BR -v ", " -r ", or " -t |
|---|
| 39 | is used, in which case it prints "You don't have any mail waiting." |
|---|
| 40 | If the |
|---|
| 41 | .B -n |
|---|
| 42 | option is used, |
|---|
| 43 | .I from |
|---|
| 44 | is always silent if there is no mail. |
|---|
| 45 | |
|---|
| 46 | .I from |
|---|
| 47 | understands the following options: |
|---|
| 48 | .TP12 |
|---|
| 49 | .B \-s \fIsender\fR |
|---|
| 50 | specifies that only headers for mail from |
|---|
| 51 | .I sender |
|---|
| 52 | are printed. |
|---|
| 53 | .TP |
|---|
| 54 | .B \-h \fIhost\fR |
|---|
| 55 | specifies that |
|---|
| 56 | .I host |
|---|
| 57 | should be consulted instead of your default post office server. |
|---|
| 58 | .TP |
|---|
| 59 | .B \-v |
|---|
| 60 | specifies that any To, Date, or Subject fields should be displayed |
|---|
| 61 | also, as well as a banner line list the number of messages waiting. |
|---|
| 62 | .TP |
|---|
| 63 | .B \-r |
|---|
| 64 | specifies that the From and Subject fields should be listed both on |
|---|
| 65 | the same line. If multiple subject fields occur in the message only |
|---|
| 66 | the first one encounter will be listed. |
|---|
| 67 | .TP |
|---|
| 68 | .B \-t |
|---|
| 69 | specifies that only the total number of messages waiting should be |
|---|
| 70 | printed. |
|---|
| 71 | .TP |
|---|
| 72 | .B \-d |
|---|
| 73 | specifies that |
|---|
| 74 | .I from |
|---|
| 75 | should run in debug mode. |
|---|
| 76 | .TP |
|---|
| 77 | .B \-u |
|---|
| 78 | specifies that only the local mail drop should be checked. |
|---|
| 79 | .TP |
|---|
| 80 | .B \-p |
|---|
| 81 | specifies that only the POP server should be checked. |
|---|
| 82 | .TP |
|---|
| 83 | .B \-? |
|---|
| 84 | specifies that usage information should be printed, no mail check |
|---|
| 85 | occurs. |
|---|
| 86 | .TP |
|---|
| 87 | .B \fIuser\fR |
|---|
| 88 | specifies that mail for |
|---|
| 89 | .I user |
|---|
| 90 | should be checked, rather than the current user. |
|---|
| 91 | .SH "FILES" |
|---|
| 92 | .TP |
|---|
| 93 | /afs/athena.mit.edu/system/config/from/ok |
|---|
| 94 | An "off switch" for the from command, to allow the postmasters to disable |
|---|
| 95 | this command if it presents too much load to the post office servers. If |
|---|
| 96 | this file is not present, ``from'' will not attempt to contact the servers |
|---|
| 97 | .TP |
|---|
| 98 | /afs/athena.mit.edu/system/config/from/message |
|---|
| 99 | If the ``ok'' file is not present (disabling the from command) the contents |
|---|
| 100 | of this file will be printed; hopefully, this will contain a message |
|---|
| 101 | informing the user as to why the command was disabled. |
