It was was removed from the kernel in 4.17. ncpfs is a network filesystem that supports the NCP protocol, Optional period and 3 character extension. msdos is the filesystem used by DOS, Windows, and some OS/2 computers.įilenames can be no longer than 8 characters, followed by an It remains useful for floppies and RAM disks. Limit, short filenames, and a single timestamp. It has a number of shortcomings, including a 64 MB partition size minix is the filesystem used in the Minix operating system, the first to run That was integrated into Linux in kernel 2.4.24. JFS is a journaling filesystem, developed by IBM, They are used to further describe the files in theįilesystem to a UNIX host, and provide information such as longįilenames, UID/GID, POSIX permissions, and devices.įilesystem support under Linux. Rock Ridge Linux also supports the System Use Sharing Protocol records specified It is automatically recognized within theįilesystem support under Linux. High Sierra Linux supports High Sierra, the precursor to the ISO 9660 standard for iso9660 is a CD-ROM filesystem type conforming to the ISO 9660 standard. Read-only under Linux due to the lack of available documentation. hpfs is the High Performance Filesystem, used in OS/2. Plus large increases in volume, file, and directory size limits.Įxt4(5). The second extended filesystem was designed as an extension of theĮxt2(5). ext2 is the high performance disk filesystem used by Linux for fixed disks It has been completely superseded by the second versionĪnd has been removed from the kernel (in 2.1.21). See the kernel documentation for a comprehensiveĭescription of all options and limitations. Short description of the available or historically available In order to use a filesystem, you have to If you need a currently unsupported filesystem, insert the corresponding That enables enumeration of the currently available filesystem types Kernel build configuration option since Linux 3.15) System call (whose availability is controlled by the Which filesystems your kernel currently supports XFS, xiafs DESCRIPTIONWhen, as is customary, the JFS, minix, msdos, ncpfs nfs, ntfs, proc, Reiserfs, smb, sysv, umsdos, vfat, Here is the output: 2022.10.Command to display fs manual in Linux: $ man 5 fs NAMEįilesystems - Linux filesystem types: ext, ext2, ext3, ext4, hpfs, iso9660, Finally, display accordingly: awk -F'\' 'NR=FNR If it already has another value, append to it with " ". If it matches and this is the first match, record the third_col value. If matched, perform the partial matching of column 2 to pattern_ht values after converting to lower case. When processing the second file, firstly check if date string matches column 1 exactly after performing a split of the key string. Since date string itself is not unique to serve as key, we will use the concatenation of columns 2 and 3 as key for both hash tables. During the first file processing, I used two hash tables, namely pattern_ht to store column 1 values in lower case and note_ht to store column 3 values. To process the first file, we could use condition NR=FNR. The BEGIN block just sets up the field separator. If no key matches, then only the line of file_B is printed. Here we print the line of file_b and the matching notes by comparing every key if the line of file_B starts with the key. In the NF!=FNR block the second file (file_B) is read. Notes are appended if the key is already existing. The NF=FNR block is used during reading the first file (file_A) here the notes are stored under a key made out of the second and first column. In the function make_key you can configure the case sensitiveness by either returning k or an uppercase version. You would use it like this: awk -f script.awk file_A file_B # either return k or an uppercase version for case-insensitive keys of the keys are case sensitive or not).Īn awk script like this might work: function make_key(k) An awk script might work depending on the details of your requirements (e.g.
