The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
fstrim-all – call fstrim on all mounted file systems which support it Description SSD drives need to be TRIMed, i. e. they need to be told which blocks the OS considers as "unused" (i. e. from deleted files). Withouth this, the write speed on SSDs becomes slower over time. fstrim-all detects which mounted partitions belong…
fstab-decode – run a command with fstab-encoded arguments Synopsis fstab-decode COMMAND [,ARGUMENT …] Description fstab-decode decodes escapes (such as newline characters and other whitespace) in the specified ARGUMENT/s and uses them to run COMMAND. The argument escaping uses the same rules as path escaping in /etc/fstab, /etc/mtab and /proc/mtab. In essence fstab-decode can be used…

fsfreeze – suspend access to a filesystem (Ext3/4, ReiserFS, JFS, XFS) Synopsis fsfreeze –freeze|–unfreeze mountpoint Description fsfreeze suspends or resumes access to a filesystem. fsfreeze halts any new access to the filesystem and creates a stable image on disk. fsfreeze is intended to be used with hardware RAID devices that support the creation of snapshots….
fsdaemon_selinux – Security Enhanced Linux Policy for the fsdaemon processes Description Security-Enhanced Linux secures the fsdaemon processes via flexible mandatory access control. The fsdaemon processes execute with the fsdaemon_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. For example: ps -eZ | grep…
fsck.xfs – do nothing, successfully Synopsis fsck.xfs [ filesys … ] Description fsck.xfs is called by the generic Linux fsck(8) program at startup to check and repair an XFS filesystem. XFS is a journaling filesystem and performs recovery at mount(8) time if necessary, so fsck.xfs simply exits with a zero exit status. If you wish…
fsck.fat – check and repair MS-DOS FAT filesystems Synopsis fsck.fat [OPTIONS] DEVICE Description fsck.fat verifies the consistency of MS-DOS filesystems and optionally tries to repair them. The following filesystem problems can be corrected (in this order): • FAT contains invalid cluster numbers. Cluster is changed to EOF. • File’s cluster chain contains a loop. The…

fsck.minix – check consistency of Minix filesystem Synopsis fsck.minix [options] device Description fsck.minix performs a consistency check for the Linux MINIX filesystem. The program assumes the filesystem is quiescent. fsck.minix should not be used on a mounted device unless you can be sure nobody is writing to it. Remember that the kernel can write to…
fsck.hfsplus – HFS file system consistency check Synopsis fsck.hfsplus –q [-df ] special … fsck.hfsplus –p [-df ] special … fsck.hfsplus [-n | y | r ] [-dfgxlE ] [-D flags ] [-b size ] [-B path ] [-m mode ] [-c size ] [-R flags ] special … Description The fsck.hfsplus utility verifies and…
fsck.gfs2 – Offline GFS and GFS2 file system checker Synopsis fsck.gfs2 [OPTION]… DEVICE Warning All computers must have the filesystem unmounted before running fsck.gfs2. Failure to unmount from all nodes in a cluster will likely result in filesystem corruption. Description fsck.gfs2 will check that the GFS or GFS2 file system on a device is structurally…
fsck.fat – check and repair MS-DOS FAT filesystems Synopsis fsck.fat [OPTIONS] DEVICE Description fsck.fat verifies the consistency of MS-DOS filesystems and optionally tries to repair them. The following filesystem problems can be corrected (in this order): • FAT contains invalid cluster numbers. Cluster is changed to EOF. • File’s cluster chain contains a loop. The…
