stat --help
Usage: stat [OPTION]... FILE...
Display file or file system status.

Mandatory arguments to long options are mandatory for short options too.
  -L, --dereference     follow links
  -f, --file-system     display file system status instead of file status
  -c  --format=FORMAT   use the specified FORMAT instead of the default;
                          output a newline after each use of FORMAT
      --printf=FORMAT   like --format, but interpret backslash escapes,
                          and do not output a mandatory trailing newline;
                          if you want a newline, include \n in FORMAT
  -t, --terse           print the information in terse form
      --help     display this help and exit
      --version  output version information and exit

The valid format sequences for files (without --file-system):

  %a   access rights in octal
  %A   access rights in human readable form
  %b   number of blocks allocated (see %B)
  %B   the size in bytes of each block reported by %b
  %C   SELinux security context string
  %d   device number in decimal
  %D   device number in hex
  %f   raw mode in hex
  %F   file type
  %g   group ID of owner
  %G   group name of owner
  %h   number of hard links
  %i   inode number
  %m   mount point
  %n   file name
  %N   quoted file name with dereference if symbolic link
  %o   optimal I/O transfer size hint
  %s   total size, in bytes
  %t   major device type in hex, for character/block device special files
  %T   minor device type in hex, for character/block device special files
  %u   user ID of owner
  %U   user name of owner
  %w   time of file birth, human-readable; - if unknown
  %W   time of file birth, seconds since Epoch; 0 if unknown
  %x   time of last access, human-readable
  %X   time of last access, seconds since Epoch
  %y   time of last modification, human-readable
  %Y   time of last modification, seconds since Epoch
  %z   time of last change, human-readable
  %Z   time of last change, seconds since Epoch

Valid format sequences for file systems:

  %a   free blocks available to non-superuser
  %b   total data blocks in file system
  %c   total file nodes in file system
  %d   free file nodes in file system
  %f   free blocks in file system
  %i   file system ID in hex
  %l   maximum length of filenames
  %n   file name
  %s   block size (for faster transfers)
  %S   fundamental block size (for block counts)
  %t   file system type in hex
  %T   file system type in human readable form

NOTE: your shell may have its own version of stat, which usually supersedes
the version described here.  Please refer to your shell's documentation
for details about the options it supports.

$ date --help
Usage: date [OPTION]... [+FORMAT]
  or:  date [-u|--utc|--universal] [MMDDhhmm[[CC]YY][.ss]]
Display the current time in the given FORMAT, or set the system date.

Mandatory arguments to long options are mandatory for short options too.
  -d, --date=STRING         display time described by STRING, not 'now'
  -f, --file=DATEFILE       like --date once for each line of DATEFILE
  -I[TIMESPEC], --iso-8601[=TIMESPEC]  output date/time in ISO 8601 format.
                            TIMESPEC='date' for date only (the default),
                            'hours', 'minutes', 'seconds', or 'ns' for date
                            and time to the indicated precision.
  -r, --reference=FILE      display the last modification time of FILE
  -R, --rfc-2822            output date and time in RFC 2822 format.
                            Example: Mon, 07 Aug 2006 12:34:56 -0600
      --rfc-3339=TIMESPEC   output date and time in RFC 3339 format.
                            TIMESPEC='date', 'seconds', or 'ns' for
                            date and time to the indicated precision.
                            Date and time components are separated by
                            a single space: 2006-08-07 12:34:56-06:00
  -s, --set=STRING          set time described by STRING
  -u, --utc, --universal    print or set Coordinated Universal Time (UTC)
      --help     display this help and exit
      --version  output version information and exit

FORMAT controls the output.  Interpreted sequences are:

  %%   a literal %
  %a   locale's abbreviated weekday name (e.g., Sun)
  %A   locale's full weekday name (e.g., Sunday)
  %b   locale's abbreviated month name (e.g., Jan)
  %B   locale's full month name (e.g., January)
  %c   locale's date and time (e.g., Thu Mar  3 23:05:25 2005)
  %C   century; like %Y, except omit last two digits (e.g., 20)
  %d   day of month (e.g., 01)
  %D   date; same as %m/%d/%y
  %e   day of month, space padded; same as %_d
  %F   full date; same as %Y-%m-%d
  %g   last two digits of year of ISO week number (see %G)
  %G   year of ISO week number (see %V); normally useful only with %V
  %h   same as %b
  %H   hour (00..23)
  %I   hour (01..12)
  %j   day of year (001..366)
  %k   hour, space padded ( 0..23); same as %_H
  %l   hour, space padded ( 1..12); same as %_I
  %m   month (01..12)
  %M   minute (00..59)
  %n   a newline
  %N   nanoseconds (000000000..999999999)
  %p   locale's equivalent of either AM or PM; blank if not known
  %P   like %p, but lower case
  %r   locale's 12-hour clock time (e.g., 11:11:04 PM)
  %R   24-hour hour and minute; same as %H:%M
  %s   seconds since 1970-01-01 00:00:00 UTC
  %S   second (00..60)
  %t   a tab
  %T   time; same as %H:%M:%S
  %u   day of week (1..7); 1 is Monday
  %U   week number of year, with Sunday as first day of week (00..53)
  %V   ISO week number, with Monday as first day of week (01..53)
  %w   day of week (0..6); 0 is Sunday
  %W   week number of year, with Monday as first day of week (00..53)
  %x   locale's date representation (e.g., 12/31/99)
  %X   locale's time representation (e.g., 23:13:48)
  %y   last two digits of year (00..99)
  %Y   year
  %z   +hhmm numeric time zone (e.g., -0400)
  %:z  +hh:mm numeric time zone (e.g., -04:00)
  %::z  +hh:mm:ss numeric time zone (e.g., -04:00:00)
  %:::z  numeric time zone with : to necessary precision (e.g., -04, +05:30)
  %Z   alphabetic time zone abbreviation (e.g., EDT)

By default, date pads numeric fields with zeroes.
The following optional flags may follow '%':

  -  (hyphen) do not pad the field
  _  (underscore) pad with spaces
  0  (zero) pad with zeros
  ^  use upper case if possible
  #  use opposite case if possible

After any flags comes an optional field width, as a decimal number;
then an optional modifier, which is either
E to use the locale's alternate representations if available, or
O to use the locale's alternate numeric symbols if available.

Examples:
Convert seconds since the epoch (1970-01-01 UTC) to a date
  $ date --date='@2147483647'

Show the time on the west coast of the US (use tzselect(1) to find TZ)
  $ TZ='America/Los_Angeles' date

Show the local time for 9AM next Friday on the west coast of the US
  $ date --date='TZ="America/Los_Angeles" 09:00 next Fri'

linux zip unzip

$ zip sample file1 file2 
  adding: file1 (stored 0%)
  adding: file2 (stored 0%)
$ ls
sample.zip  file1  file2

unzip sample.zip -d /var/www/html

nzip

UnZip 6.00 of 20 April 2009, by Debian. Original by Info-ZIP.

Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]

Default action is to extract files in list, except those in xlist, to exdir;

file[.zip] may be a wildcard. -Z => ZipInfo mode ("unzip -Z" for usage).

-p extract files to pipe, no messages -l list files (short format)

-f freshen existing files, create none -t test compressed archive data

-u update files, create if necessary -z display archive comment only

-v list verbosely/show version info -T timestamp archive to latest

-x exclude files that follow (in xlist) -d extract files into exdir

modifiers:

-n never overwrite existing files -q quiet mode (-qq => quieter)

-o overwrite files WITHOUT prompting -a auto-convert any text files

-j junk paths (do not make directories) -aa treat ALL files as text

-U use escapes for all non-ASCII Unicode -UU ignore any Unicode fields

-C match filenames case-insensitively -L make (some) names lowercase

-X restore UID/GID info -V retain VMS version numbers

-K keep setuid/setgid/tacky permissions -M pipe through "more" pager

-O CHARSET specify a character encoding for DOS, Windows and OS/2 archives

-I CHARSET specify a character encoding for UNIX and other archives

See "unzip -hh" or unzip.txt for more help. Examples:

unzip data1 -x joe => extract all files except joe from zipfile data1.zip

unzip -p foo | more => send contents of foo.zip via pipe into program more

unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer
