line 76 sais:
mimeType=`file --mime "$1" | cut -d: -f2-`
this is wrong. mimeType variable always contains a whitespace at first position.
for example:
mimeType=" image/png"
for that reason the code in line 93 until 112 is never executed.
it consists of commands like this:
type = "jfif"
this is not legal shell code!
correct would be:
type="jfif" (without whitespace)
but due to the first bug, this wrong code is never executed. as i fixed the
first bug the script bailed out at the second bug ;)
isn't it strange that such an error can last for years without ever being
noticed ;) never executed untested code.... :-)
i found this bug, because i have a PNG image file with the following strange
behaviour:
erik@goofy:~/filebug$ file --mime 28
28: image/png
erik@goofy:~/filebug$ file 28
28: Minix filesystem
erik@goofy:~/filebug$
the file utility uses two different databases for mime output and human readable
output. in the mime database there is no "minix file type" and in the human
readable database there is a minix file type. unfortunately file gives favour
for minix over png, but that is another discussion.
anyway what anytopnm sais here is:
erik@goofy:~/filebug$ anytopnm 28
/usr/bin/anytopnm: unknown file type. 'file' says mime type is ' image/png',
type description is ' Minix filesystem'
you see the whitespaces??? these whitespaces confuse anytopnm.
normaly anytopnm would see that
file --mime myfile
returns
image/png
and just go on read the file. but the mime type is always ignored by the script
due to the bug in the "cut" statement. instead the script ALWAYS uses the human
readable description and in this case the human readable description is wrong,
so the script fails.
Reproducible: Always
