NAME

e2recover − attempt to recover deleted files on ext2 file systems

SYNOPSIS

e2recover [options]... [lsdel-files]...

DESCRIPTION

e2recover attempts to recover deleted files from an ext2 file system, using the output (in lsdel-files) from the ‘lsdel’ command in debugfs(1). Standard input is read if no file names are given, or on a file name of ‘−’. Recovered files are written to the appropriate temporary directory, with names like e2rec.pid.dev.inum. It uses the environment variables $FSGRAB and $DEBUGFS to find those programs, or looks in $PATH if they are unset.

More information on e2recover (including a description of how it works its magic, and the situations in which it fails) are available on the author’s website.

OPTIONS

−d, −−device=device

Read data from device instead of the default /dev/hda1.

−b, −−block-size=blocksize

Use a block size of blocksize instead of the default 1024 bytes. blocksize may have an optional multiplier suffix: w for ×2, b for ×512, k for ×1024, m for ×1Meg.

−t, −−tmpdir, −−tempdir=tmpdir

Write recovered files to tmpdir instead of the default ${TMPDIR:-/tmp}.

−g, −−guess-indirects

Try to recover files with zeroed indirect blocks by assuming that there was no fragmentation in the file. Unless the files were deleted under a Linux 2.1.x or 2.2.x kernel, you will normally want to specify this option, though how useful it is will depend on a wide variety of environmental factors.

−−help

Write a usage message to standard output and exit successfully.

−−version

Write version information to standard output and exit successfully.
