HELP：ASMCMD

By Adamhuan | 2017年2月28日

ASMCMD命令的帮助信息：

[vcdgrid@oracle scripts]$ asmcmd help
        
            asmcmd [-V] [-v <errors|warnings|normal|info|debug>] [--privilege <sysasm|sysdba>] [-p] [command]
asmcmd_no_conn_str

        Starts asmcmd or executes the command

        asmcmd [-V] [-v <errors|warnings|normal|info|debug>] [--privilege <sysasm|sysdba>] [-p] [command]

        The environment variables ORACLE_HOME and ORACLE_SID determine the 
        instance to which the program connects, and ASMCMD establishes a 
        bequeath connection to it, in the same manner as a SQLPLUS / AS 
        SYSASM.  The user must be a member of the OSASM group.

        Specifying the -V option prints the asmcmd version number and
        exits immediately.

        Specifying the -v option prints extra information that can help
        advanced users diagnose problems.

        Specify the --privilege option to choose the type of connection. There are
        only two possibilities: connecting as SYSASM or as SYSDBA.
        The default value if this option is unspecified is SYSASM.

        Specifying the -p option allows the current directory to be displayed 
        in the command prompt, like so:

        ASMCMD [+DATA/ORCL/CONTROLFILE] >

        [command] specifies one of the following commands, along with its
        parameters.

        Type "help [command]" to get help on a specific ASMCMD command.';

        commands:
        --------

        md_backup, md_restore

        lsattr, setattr

        cd, cp, du, find, help, ls, lsct, lsdg, lsof, mkalias
        mkdir, pwd, rm, rmalias

        chdg, chkdg, dropdg, iostat, lsdsk, lsod, mkdg, mount
        offline, online, rebal, remap, umount

        dsget, dsset, lsop, shutdown, spbackup, spcopy, spget
        spmove, spset, startup

        chtmpl, lstmpl, mktmpl, rmtmpl

        chgrp, chmod, chown, groups, grpmod, lsgrp, lspwusr, lsusr
        mkgrp, mkusr, orapwusr, passwd, rmgrp, rmusr

        volcreate, voldelete, voldisable, volenable, volinfo
        volresize, volset, volstat

Linux MAN：Command，sort

By Adamhuan | 2015年12月19日

命令：sort的帮助信息如下：

[root@localhost ~]# sort --help
Usage: sort [OPTION]... [FILE]...
Write sorted concatenation of all FILE(s) to standard output.

Mandatory arguments to long options are mandatory for short options too.
Ordering options:

  -b, --ignore-leading-blanks  ignore leading blanks
  -d, --dictionary-order      consider only blanks and alphanumeric characters
  -f, --ignore-case           fold lower case to upper case characters
  -g, --general-numeric-sort  compare according to general numerical value
  -i, --ignore-nonprinting    consider only printable characters
  -M, --month-sort            compare (unknown) < `JAN' < ... < `DEC'
  -n, --numeric-sort          compare according to string numerical value
  -r, --reverse               reverse the result of comparisons

Other options:

  -c, --check               check whether input is sorted; do not sort
  -k, --key=POS1[,POS2]     start a key at POS1, end it at POS2 (origin 1)
  -m, --merge               merge already sorted files; do not sort
  -o, --output=FILE         write result to FILE instead of standard output
  -s, --stable              stabilize sort by disabling last-resort comparison
  -S, --buffer-size=SIZE    use SIZE for main memory buffer
  -t, --field-separator=SEP  use SEP instead of non-blank to blank transition
  -T, --temporary-directory=DIR  use DIR for temporaries, not $TMPDIR or /tmp;
                              multiple options specify multiple directories
  -u, --unique              with -c, check for strict ordering;
                              without -c, output only the first of an equal run
  -z, --zero-terminated     end lines with 0 byte, not newline
      --help     display this help and exit
      --version  output version information and exit

POS is F[.C][OPTS], where F is the field number and C the character position
in the field.  OPTS is one or more single-letter ordering options, which
override global ordering options for that key.  If no key is given, use the
entire line as the key.

SIZE may be followed by the following multiplicative suffixes:
% 1% of memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.

With no FILE, or when FILE is -, read standard input.

*** WARNING ***
The locale specified by the environment affects sort order.
Set LC_ALL=C to get the traditional sort order that uses
native byte values.

Report bugs to <bug-coreutils@gnu.org>.
