ex(1) -- extended line-oriented text editor
|
The ex program is the line-oriented personality of a text editor that also supports screen-oriented editing (see vi(1)). (XPG4 only.) Certain block-mode terminals do not have all the capabilities necessary to support the complete ex definition, such as the full-screen editing commands (visual mode or open mode). When these commands cannot be supported on such terminals, this condition shall neithe... |
exit(1m) -- Causes dtscp to complete execution.
|
The exit command causes the DTS control program (dtscp) to complete execution and returns operation to the parent process. |
|
expand(1) -- expand tabs to spaces, and vice versa
|
expand processes the named files or the standard input and writes to the standard output with tabs changed into spaces. Backspace characters are preserved in the output, and the column count is decreased by one column for tab calculations. For proper tab calculation, if a multi-column character is to be "backspace'd", it should be followed by multiple backspace characters which equal to it's c... |
expand_alias(1) -- recursively expands the sendmail aliases
|
Expand_alias is a shell script that recursively expands the sendmail aliases. Through use of telnet host 25 and the expn command, each alias is recursively expanded into its destination(s). Indentation is used to show each level of recursion. Because of the recursive use of telnet, expand_alias is slow. If the local telnet cannot directly connect to a remote system, due to a firewall configuration... |
exportfs(1m) -- export and unexport directories to NFS clients
|
The exportfs command makes a local directory or file available to NFS clients for mounting over the network. Directories and files cannot be NFS-mounted unless they are first exported by exportfs. exportfs is normally invoked at boot time by the /sbin/init.d/nfs.server script, and uses information contained in the /etc/exports file to export the file or file system named by each dir, which must be... |
expr(1) -- evaluate arguments as an expression
|
expr takes arguments as an expression, evaluates, then writes the result on the standard output. Terms in the expression must be separated by blanks. Characters special to the shell must be escaped. Note that 0, rather than the null string, is returned to indicate a zero value. Strings containing blanks or other special characters should be quoted. Integer-valued arguments can be preceded by a una... |
extendfs(1m) -- extend a file system size (generic)
|
If the original file system image created on special does not make use of all of the available space, extendfs can be used to increase the capacity of a file system by updating the file system structure to include the extra space. The command-line parameter special specifies the device special file of either a logical volume or a disk partition. The special must be un-mounted before extendfs can b... |
extendfs_hfs(1m) -- extend HFS file system size
|
If the original HFS file system image created on special does not make use of all of the available space, the extendfs command can be used to increase the capacity of an HFS file system by updating the file system structure to include the extra space. The command-line parameter special specifies the character device special file of either a logical volume or a disk partition. The special must be u... |
extendfs_vxfs(1m) -- extend VxFS file system size
|
If the VxFS file system image created on special does not use all of the available space, extendfs increases the capacity of a VxFS file system by updating the file system structure to include the extra space. special specifies the device special file of either a logical volume or a disk partition. If special refers to a mounted file system, you must unmount special before running extendfs (see mo... |
factor(1) -- factor a number, generate large primes
|
If no arguments are provided on the command line, factor waits for a number to be typed in. If a positive number is typed, it factors the number and print its prime factors; each one is printed the proper number of times. It then waits for another number. factor exits if it encounters a zero or any non-numeric character. If an argument is provided on the command line, factor factors the number as ... |
false(1) -- return exit status zero or one respectively
|
The command true does nothing, and returns exit code zero. The command false does nothing, and returns exit code one. They are typically used to construct command procedures. |
fastbind(1) -- Prepare an incomplete executable for faster program startup
|
fastbind is a tool that can improve the start-up time of programs that use shared libraries (incomplete executables) by storing information about needed shared library symbols in the executable file. fastbind performs analysis on the symbols used to bind an executable and all of it's dependent shared libraries, and stores this information in the executable file. The next time the executable is ru... |
fastmail(1) -- quick batch mail interface
|
The fastmail command is a simple interface to the mail system that allows you to send a message without the overhead of an interactive mailer. It is particularly efficient in batch-processing mail to very large groups of people. All addresses should be full e-mail addresses, sendmail aliases in the /etc/mail/aliases file, or local login names. |
fbackup(1m) -- selectively back up files
|
fbackup combines features of dump and ftio to provide a flexible, high-speed file system backup mechanism (see dump(1M) and ftio(1)). fbackup selectively transfers files to an output device. For each file transferred, the file's contents and all the relevant information necessary to restore it to an equivalent state are copied to the output device. The output device can be a raw magnetic tape dri... |
