Hello dpontius,

Can you get the output from ls -li in the directory? That should list the inode number in the first column. You could then use find like this:-

Code:
/tmp/tmp.jwq73hdq # ls -li
total 0
2360780 -rw-rw-r-- 1 rbatte1 rbatte1 0 Jul 19 08:54 ␀␀Word Finder® Plus™
/tmp/tmp.jwq73hdq # find . -inum 2360780 -exec rm {} \;
/tmp/tmp.jwq73hdq # ls -li
total 0
/tmp/tmp.jwq73hdq #


Does that help? If not, what does the output of lsattr give you?
Code:
/tmp/tmp.jwq73hdq # rm *
rm: remove write-protected regular empty file `␀␀Word Finder® Plus™'? y
rm: cannot remove `␀␀Word Finder® Plus™': Operation not permitted
/tmp/tmp.jwq73hdq # lsattr
----i--------e- ./␀␀Word Finder® Plus™
/tmp/tmp.jwq73hdq # chattr -i *
/tmp/tmp.jwq73hdq # rm *
/tmp/tmp.jwq73hdq #

...... maybe even a combination of this then the find might be needed.



I hope that this helps,
Robin

cdbmake(1)						      General Commands Manual							cdbmake(1)

NAME
cdbmake - create a constant database SYNOPSIS
cdbmake cdb cdb.tmp DESCRIPTION
cdbmake reads a series of encoded records from its standard input and writes a constant database to cdb. cdbmake ensures that cdb is updated atomically, so programs reading cdb never have to wait for cdbmake to finish. It does this by first writing the database to cdb.tmp and then moving cdb.tmp on top of cdb. If cdb.tmp already exists, it is destroyed. The directories con- taining cdb.tmp and cdb must be writable to cdbmake; they must also be on the same filesystem. cdbmake always makes sure that cdb.tmp is safely written to disk before it replaces cdb. If the input is in a bad format or if cdbmake has any trouble writing cdb.tmp to disk, cdbmake complains and leaves cdb alone. RECORD FORMAT Records are indexed by keys. A key is a string. cdb is structured so that another program, starting from a key, can quickly find the rel- evant record. cdbmake allows several records with the same key, although most readers take only the first record, and cdbmake slows down somewhat if there are many records with the same key. cdbmake and cdbdump(1) preserve the order of records. A record is encoded for cdbmake as +klen,dlen:key->data followed by a newline. Here klen is the number of bytes in key and dlen is the number of bytes in data. The end of data is indicated by an extra newline. For example: +3,5:one->Hello +3,7:two->Goodbye key and data may contain any characters, including colons, dashes, newlines, and nulls. Keys and data do not have to fit into memory. A database cannot exceed 4 gigabytes. cdb is portable across machines. SEE ALSO
