SPLIT(1)               DragonFly General Commands Manual              SPLIT(1)

NAME
     split - split a file into pieces

SYNOPSIS
     split -d [-a suffix_length] [-b byte_count[suffix]] [-l line_count]
           [-p pattern] [file [name]]

DESCRIPTION
     The split utility reads the given file and breaks it up into files of
     1000 lines each.  If file is a single dash (`-') or absent, split reads
     from the standard input.

     The options are as follows:

     -a suffix_length
             Use suffix_length letters to form the suffix of the file name.

     -b byte_count[suffix]
             Create smaller files byte_count bytes in length.  An optional
             suffix (as documented in dehumanize_number(3)) is supported.

     -d      Use a numeric suffix instead of an alphabetic suffix.

     -l line_count
             Create smaller files n lines in length.

     -p pattern
             The file is split whenever an input line matches pattern, which
             is interpreted as an extended regular expression.  The matching
             line will be the first line of the next output file.  This option
             is incompatible with the -b and -l options.

     If additional arguments are specified, the first is used as the name of
     the input file which is to be split.  If a second additional argument is
     specified, it is used as a prefix for the names of the files into which
     the file is split.  In this case, each file into which the file is split
     is named by the prefix followed by a lexically ordered suffix using
     suffix_length characters in the range "a-z".  If -a is not specified, two
     letters are used as the suffix.

     If the name argument is not specified, the file is split into lexically
     ordered files named with prefix "x" and with suffixes as above.

     re_format(7)

STANDARDS
     The split utility conforms to IEEE Std 1003.1-2001 ("POSIX.1").

HISTORY
     A split command appeared in Version 3 AT&T UNIX.

BUGS
     The maximum line length for matching patterns is 65536.

NAME
       split - Split a string into a proper Tcl list

SYNOPSIS
       split string ?splitChars?
______________________________________________________________________________

DESCRIPTION
       Returns a list created by splitting string at each character that is in
       the splitChars argument.  Each element of the result list will consist
       of the characters from string that lie between instances of the
       characters in splitChars.  Empty list elements will be generated if
       string contains adjacent characters in splitChars, or if the first or
       last character of string is in splitChars.  If splitChars is an empty
       string then each character of string becomes a separate element of the
       result list.  SplitChars defaults to the standard white-space
       characters.

EXAMPLES
       Divide up a USENET group name into its hierarchical components:

              split "comp.lang.tcl" .
                    -> comp lang tcl

       See how the split command splits on every character in splitChars,
       which can result in information loss if you are not careful:

              split "alpha beta gamma" "temp"
                    -> al {ha b} {} {a ga} {} a

       Extract the list words from a string that is not a well-formed list:

              split "Example with {unbalanced brace character"
                    -> Example with \{unbalanced brace character

       Split a string into its constituent characters

              split "Hello world" {}
                    -> H e l l o { } w o r l d

   PARSING RECORD-ORIENTED FILES
       Parse a Unix /etc/passwd file, which consists of one entry per line,
       with each line consisting of a colon-separated list of fields:

              ## Read the file
              set fid [open /etc/passwd]
              set content [read $fid]
              close $fid

              ## Split into records on newlines
              set records [split $content "\n"]

              ## Iterate over the records
              foreach rec $records {

                  ## Split into fields on colons
                  set fields [split $rec ":"]

                  ## Assign fields to variables and print some out...
                  lassign $fields \
                          userName password uid grp longName homeDir shell
                  puts "$longName uses [file tail $shell] for a login shell"
              }
