| 3 | Maintenance notes:
|
|---|
| 4 |
|
|---|
| 5 | I am continuing to maintain the file command. I welcome your help,
|
|---|
| 6 | but to make my life easier I'd like to request the following:
|
|---|
| 7 |
|
|---|
| 8 | - Do not distribute changed versions.
|
|---|
| 9 |
|
|---|
| 10 | People trying to be helpful occasionally put up their hacked versions
|
|---|
| 11 | of the file command for anonymous FTP, and people all over the
|
|---|
| 12 | world get copies of the hacked versions. Within a day or two I am
|
|---|
| 13 | getting email from around the world asking me why "my" file command
|
|---|
| 14 | won't compile!!! Needless to say this detracts from the limited
|
|---|
| 15 | time I have available to work on the actual software. Therefore I
|
|---|
| 16 | ask you again to please NOT distribute your changed version. If
|
|---|
| 17 | you need to make changes, please add a patch file next to the
|
|---|
| 18 | distribution tar, and a README file that clearly explains what you
|
|---|
| 19 | are trying to fix.
|

|

| 21 | Thank you for your assistance and cooperation.

| 23 | Code Overview
|
|---|
| 24 |
|
|---|
| 25 | This is a rough idea of the control flow from the main program:
|
|---|
| 26 |
|
|---|
| 27 | file.c main()
|
|---|
| 28 | file.c process (called for each file)
|
|---|
| 29 | printf file name
|
|---|
| 30 | magic.c magic_file()
|
|---|
| 31 | fsmagic.c file_fsmagic()
|
|---|
| 32 | (handles statbuf modes for DEV)
|
|---|
| 33 | (handles statbuf modes for executable &c.
|
|---|
| 34 | reads data from file.
|
|---|
| 35 | funcs.c: file_buffer()
|
|---|
| 36 | compress.c file_zmagic()
|
|---|
| 37 | is_tar.c file_is_tar()
|
|---|
| 38 | softmagic.c file_softmagic()
|
|---|
| 39 | match() - looks for match against main magic database
|
|---|
| 40 | ascmagic.c file_ascmagic()
|
|---|
| 41 | readelf.c file_tryelf()
|
|---|
| 42 | "unknown"
|
