I don't recall what the other partitions are sized at by default. If you didn't delete your last few daily output mails, you may still have the df output there, such as: Disk status: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/wd0s2a 124015 26338 87756 23% / /dev/wd0s2f 2480982 627548 1654956 27% /usr /dev/wd0s2g 7103813 21826 6513682 0% /usr/local /dev/wd0s2e 297663 1350 272500 0% /var procfs 4 4 0 100% /proc I have a program which could help you recover that particular message. I've attached the C file here. Please note I am offering it without any warranty whatsoever. :-) I'm certain there are better ways to do it than byte-by-byte matching. Its usage is as follows: ./search "string" file-or-device mask.%s For example, in this case you could do: ./search "Disk status:" /dev/wd0s1c /root/df.%s (I've lost the original e-mail, so I don't recall if this is IDE or SCSI. Either way, you want to search partition c.) It takes a long time to run, but it will notify you when it gets matches so you can possibly abort it prematurely. In this example, it would save the output in /root/df.0000001 and up. Btw, if you wanted to recover the entire root mailbox, search for "From " (with the extra space) --0-1987189661-1003856416=:85958 Content-Type: TEXT/PLAIN; charset=US-ASCII; name="search.c" Content-Transfer-Encoding: BASE64 Content-ID: <20011023100016.Q85958@localhost> Content-Description: search.c Content-Disposition: attachment; filename="search.c" LyoNCiAqICJncmVwcyIgZm9yIGEgc3RyaW5nLCBhbmQgd3JpdGVzIG91dCBh bnkgbWF0Y2hlcyAodXAgdG8gYSBOVUxMKQ0KICogdXNlZnVsIGZvciBleHRy YXRpbmcgc2NyaXB0cyBhbmQgaHRtbCBmcm9tIG90aGVyd2lzZSB1bnVzYWJs ZQ0KICogZHJpdmVzLg0KICoNCiAqIGZ1dHVyZSBlbmhhbmNlbWVudHM6DQog KiAgcmVndWxhciBleHByZXNzaW9uIG1hdGNoaW5nDQogKi8NCg0KI2luY2x1 ZGUgPHN0ZGlvLmg+DQojaW5jbHVkZSA8c3RkbGliLmg+DQojaW5jbHVkZSA8 c3lzL3R5cGVzLmg+DQojaW5jbHVkZSA8c3lzL3N0YXQuaD4NCiNpbmNsdWRl IDxmY250bC5oPg0KI2luY2x1ZGUgPGVycm5vLmg+DQoNCnN0YXRpYyBjaGFy IGlkZW50W10gPSAiJElkOiBzZWFyY2guYyx2IDEuMiAyMDAxLzA4LzI0IDE2 OjM1OjQxIGRhdmlkayBFeHAgJCI7DQoNCmludA0KbWFpbiAoYXJnYywgYXJn dikNCglpbnQJYXJnYzsNCgljaGFyCSphcmd2W107DQp7DQoJY2hhcgkqc2Vh cmNoOw0KCWNoYXIJKmZuYW1lOw0KCWNoYXIJKm91dHB1dG1hc2s7DQoJY2hh cglvZm5hbWVbNDA5Nl07DQoJaW50CW1hdGNoID0gMDsNCgljaGFyCW1hdGNo X3NbOF07DQoJaW50CWZkOw0KCWludAlvZmQ7DQoJY2hhcglidWZbMl07DQoJ Y2hhcgkqcHRyOw0KCWxvbmcgbG9uZwlsb2MgPSAwOw0KDQoJaWYgKGFyZ2Mg IT0gNCkgew0KCQlmcHJpbnRmIChzdGRlcnIsICJ1c2FnZTogc2VhcmNoIFwi c3RyaW5nXCIgZmlsZSBvdXRwdXRtYXNrXG4iKTsNCgkJZXhpdCAoMSk7DQoJ fQ0KDQoJc2VhcmNoID0gYXJndlsxXTsNCglmbmFtZSA9IGFyZ3ZbMl07DQoJ b3V0cHV0bWFzayA9IGFyZ3ZbM107DQoJaWYgKG91dHB1dG1hc2tbMF0gPT0g J1wwJyB8fCAhc3Ryc3RyIChvdXRwdXRtYXNrLCAiJXMiKSkgew0KCQlmcHJp bnRmIChzdGRlcnIsICJvdXRwdXRtYXNrIG11c3QgY29udGFpbiBvbmUgJSVz XG4iKTsNCgkJZXhpdCAoMSk7DQoJfQ0KDQoJZmQgPSBvcGVuIChmbmFtZSwg T19SRE9OTFkpOw0KCWlmIChmZCA8IDApIHsNCgkJZnByaW50ZiAoc3RkZXJy LCAiJXM6ICVzXG4iLCBmbmFtZSwgc3RyZXJyb3IgKGVycm5vKSk7DQoJCWV4 aXQgKDEpOw0KCX0NCg0KCXB0ciA9IHNlYXJjaDsNCgl3aGlsZSAoKHJlYWQg KGZkLCBidWYsIDEpKSA+IDApIHsNCgkJaWYgKGJ1ZlswXSA9PSAqcHRyKSB7 DQoJCQlwdHIrKzsNCgkJCWlmICgqcHRyID09ICdcMCcpIHsNCgkJCQkvKiB3 ZSBmb3VuZCBhIG1hdGNoICovDQoJCQkJcHJpbnRmICgibWF0Y2ggKCVzKSFc biIsIHNlYXJjaCk7DQoJCQkJbWF0Y2grKzsNCgkJCQlzcHJpbnRmIChtYXRj aF9zLCAiJTA3ZCIsIG1hdGNoKTsNCgkJCQlzcHJpbnRmIChvZm5hbWUsIG91 dHB1dG1hc2ssIG1hdGNoX3MpOw0KCQkJCXByaW50ZiAoIndyaXRpbmcgdG8g JXNcbiIsIG9mbmFtZSk7DQoJCQkJb2ZkID0gb3BlbiAob2ZuYW1lLCBPX1dS T05MWXxPX0NSRUFUfE9fVFJVTkMsIFNfSVJVU1J8U19JV1VTUik7DQoJCQkJ aWYgKG9mZCA8IDApIHsNCgkJCQkJZnByaW50ZiAoc3RkZXJyLCAiJXM6ICVz XG4iLCBvZm5hbWUsIHN0cmVycm9yIChlcnJubykpOw0KCQkJCX0NCgkJCQlp ZiAoKHdyaXRlIChvZmQsIHNlYXJjaCwgc3RybGVuIChzZWFyY2gpKSkgPCAw KSB7DQoJCQkJCWZwcmludGYgKHN0ZGVyciwgIiVzOiAlc1xuIiwgb2ZuYW1l LCBzdHJlcnJvciAoZXJybm8pKTsNCgkJCQl9DQoJCQkJd2hpbGUgKHJlYWQg KGZkLCBidWYsIDEpID4gMCAmJiBidWZbMF0gIT0gJ1wwJykgew0KCQkJCQlp ZiAoKHdyaXRlIChvZmQsIGJ1ZiwgMSkpIDwgMCkgew0KCQkJCQkJDQoJCQkJ CQlmcHJpbnRmIChzdGRlcnIsICIlczogJXNcbiIsIG9mbmFtZSwgc3RyZXJy b3IgKGVycm5vKSk7DQoJCQkJCX0NCgkJCQkJbG9jKys7DQoJCQkJfQ0KCQkJ CWNsb3NlIChvZmQpOw0KCQkJCXB0ciA9IHNlYXJjaDsNCgkJCX0NCgkJfSBl bHNlIHsNCgkJCXB0ciA9IHNlYXJjaDsNCgkJfQ0KCQlpZiAobG9jICUgMTYz ODQgPT0gMCkgew0KCQkJaWYgKGxvYyAlIDEwNDg1NzYgPT0gMCkgew0KCQkJ CWZwcmludGYgKHN0ZGVyciwgIi4lbGQiLCBsb2MpOw0KCQkJfSBlbHNlIHsN CgkJCQlmcHV0YyAoJy4nLCBzdGRlcnIpOw0KCQkJfQ0KCQl9DQoJCWxvYysr Ow0KCX0NCn0NCg== --0-1987189661-1003856416=:85958-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
