I'm using debugfs to stat a filename with spaces. The file exists, but I get this message (same message if I change spaces by \ or write the filename between simple quotes):

$ sudo debugfs -R "stat /home/user/This is a test.txt" /dev/mapper/VolGroup00-lv_root
debugfs 1.44.5 (15-Dec-2018)
stat: Usage: stat <file>

If I use this format I get this error:

$ sudo debugfs -R "stat $'/home/user/This\x20is\x20a\x20test.txt'" /dev/mapper/VolGroup00-lv_root 
debugfs 1.44.5 (15-Dec-2018)
$'/home/user/This\x20is\x20a\x20test.txt': File not found by ext2_lookup

If I use this format I get this error:

$ sudo debugfs -R "stat $'/home/user/This\024is\024a\024test.txt'" /dev/mapper/VolGroup00-lv_root 
debugfs 1.44.5 (15-Dec-2018)
$'/home/user/This\024is\024a\024test.txt': File not found by ext2_lookup

Is it possible to stat a filename with spaces with debugfs?

stat in debugfs expects exactly one argument (therefore Usage: stat <file>). The string you provided

/home/user/This is a test.txt

is seen as many arguments separated by spaces. The tool supports quoting with double quotes though. This will work:

sudo debugfs -R 'stat "/home/user/This is a test.txt"' /dev/mapper/VolGroup00-lv_root

  • Sorry, but I tink that I tested it before and does not work $ sudo debugfs -R 'stat "/home/user/This is a test.txt"' /dev/mapper/VolGroup00-lv_root debugfs 1.44.5 (15-Dec-2018) /home/user/This is a test.txt: File not found by ext2_lookup

  • @oml Apparently there is no such file but the syntax is now correct. The response shows all spaces in the filename were recognized.
