Well, I have umbumtwo at home, if I boot over. What are the file names like:
Code:
ls -l|cat -vte | line

and what do the innards of the info files look like:
Code:
cat -vte <info_file_for_file_from_above>

?

As you understand the deleted files can be any file, the info files of these files looks like:
Code:
[Trash Info]
Path=/home/alex/Desktop/adf
DeletionDate=2010-10-28T00:01:50

I don't know how to get the Path. All other are known. Smilie

hi,
try this:
Code:
find . -type f -exec grep "Path" {} \;

i got output as follows:
Code:
Path=/home/user1/Pictures/Webcam/2010-06-14-203606.jpg
Path=/home/user1/.google/picasa/3.0/dosdevices/z:/home/user1/Desktop/collate/IMG_0197.JPG
Path=/home/user1/.google/picasa/3.0/dosdevices/z:/home/user1/Desktop/collate/IMG_0212.JPG

Are you trying to convert a possible relative path to an absolute path?

Code:
$ readlink -m myfile.txt
/home/chubler/myfile.txt

$ readlink -m /tmp/chub.tmp
/tmp/chub.tmp

readlink does the work. Thank you very much!

The more general solution is realpath, which will take any sort of path and give you an absolute path without sym-links.

Man Page for realpath (All Section 1) - The UNIX and Linux Forums

I coded my own for systems lacking it:

Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <limits.h>

main( int argc, char **argv )
{
	char	buf[PATH_MAX+1];
	char	obuf[PATH_MAX+1];
	char	*cp ;
	int	i = 1 ;

	while (  (  i < argc
                 && (  strcpy( buf, argv[i++] )
                    || 1 ) )
              || ( i == 1
		 && fgets( buf, sizeof( buf ), stdin ) ) )
	{
		if ( cp = strchr( buf, '\n' ) )
		{
			*cp = NULL ;
		}

		if ( !realpath( buf, obuf ) )
		{
			fflush( stdout );
			fputs( "realpath() failure: ", stderr );
			perror( buf );
			continue ;
		}

		if ( 0 > printf( "%s\n", obuf ) )
		{
			if ( ferror( stdout ) )
			{
				perror( "stdout" );
				exit( 1 );
			}

			exit( 0 );
		}
	}

	if ( ferror( stdin ) )
	{
		fflush( stdout );
		perror( "stdin" );
		exit( 1 );
	}

	exit( 0 );
}

Could also be implemented as a ksh/bash script:

Code:
fname=${1%/} # strips trailing '/'
while [ -L "$fname" ]; do
    oldfname="${fname}"
    fname="$(command ls -l $fname)"
    fname="${fname#*> }"
    if [ "$fname" = . ] ; then
        fname="${oldfname##*/}"
    elif [ "${fname#/}" = "${fname}" ]; then
        d=${oldfname#/}
        d=/${d%%/*}
        fname="${d}/$fname"
    fi
done
d=${fname%/*}
d=$([ -d "${d:-/}" ] && cd ${d:-/} ; pwd -P)
echo ${d%/}/${fname##*/}
