Code:

ls -ltd $( find . -mtime -1 )

is nice for one day if you do not swamp ls's file count limit, else see above.

Space can disappear into files being actively appended, so fuser on large, growing files will show the process that is writing.

Space can disappear into huge directories, which have to be recreated to get the space back.

Space can disappear into many new little files, which can be helped a lot with zip archiving!

-exec is a bit slow (a fork/exec per hit), so try:

Code:

find . . . | xargs -n999 ls -l

Your -t was a misfiring neuron, as a one file list is always sorted.

Code:

ls -ltd $( find . -mtime -1 )

is nice for one day if you do not swamp ls's file count limit, else see above. Time sorting can be made more versatile and robust if you can put mtime with the file name and sort -n, so I wrote a stat() wrapper mystat.c that reads file names from stdin and writes mtime\tfile_name\n to stdout.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <limits.h>
#include <string.h>
#include <sys/types.h>
#include <sys/stat.h>
 
static void psf( char * buf )
{
    struct stat64 s ;
 
    if ( 0 > stat64( buf, &s ) )
    {
        perror( buf );
        return ; ;
    }
 
    if ( 0 > printf( "%u\t%s\n", s.st_mtime, buf ) )
    {
        if ( !ferror( stdout ) )
            exit( 0 );
        perror( "stdout" );
        exit( 1 );
    }
}
 
int main( int argc, char **argv )
{
    char buf[PATH_MAX + 2];
    char *cp ;
    int i ;
    int clf = 0 ;
 
    for ( i = 1 ; i < argc ; i++ )
    {
        clf ++ ;
        psf( argv[i] );
    }
 
    if ( !clf ) while ( fgets( buf, sizeof buf, stdin ) )
    {
        if ( !( cp = strchr( buf, '\n' ) ) )
        {
            fprintf( stderr, "File path too long: '%s'\n", buf );
            continue ;
        }
 
        *cp = NULL ;
        psf( buf );
    }
 
    if ( !ferror( stdin ) )
        exit( 0 );
 
    perror( "stdin" );
    exit( 1 );
}
