awk inside shell and script aborting
Hi
I have a requirement where i need to convert the xml in various lines into a single line and then split the file so that the file contains only 1000 records each.

searching this forum, i found a command which converts the xml in various line
into a single line, but i have trouble using that in the shell script, as the script
reads the parameters variables as commands..

below is the command i found

Code:
awk '/<cmk:Service/{ORS="";if(NR!=1)print "\n";}1' /data/file1.xml > /data/file2.txt

below is the script i prepared, its aborting with
Code:
Service: not found, no such file or directory

Code:
$1 = /<cmk:Service/
$2 = /data
$3 = file1.xml
$4 = file2.txt
$ = file ( prefix for split command)

Code:
#!/bin/sh
awk '$1{ORS="";if(NR!=1)print "\n";}1' $2/$3 > $2/$4
split -l 1000 $2/$3 $5

for i in $( ls $5* )
timestamp=`date "+%Y%m%d%H%M%S"`
do
mv -f $5* $5_$timestamp_$i.dat
done

can someone help me on this?

thanks
MJ

split

SPLIT(1)						    BSD General Commands Manual 						  SPLIT(1)

NAME

     split -- split a file into pieces

SYNOPSIS

     split [-a suffix_length] [-b byte_count[k|m]] [-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[k|m]
	     Create smaller files byte_count bytes in length.  If ``k'' is appended to the number, the file is split into byte_count kilobyte
	     pieces.  If ``m'' is appended to the number, the file is split into byte_count megabyte pieces.

     -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 speci-
     fied, two letters are used as the suffix.

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

ENVIRONMENT

     The LANG, LC_ALL, LC_CTYPE and LC_COLLATE environment variables affect the execution of split as described in environ(7).

EXIT STATUS

     The split utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     csplit(1), 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.
