Another scripting help please, splitting files by range, maybe I don't need a script :(

Hi,


I requested the Windows SysAdmin to give me all available config files from a server.



Instead of sending it into several files, he combine all of them into one single file leaving it for me to split them up myself.


I was able to do so via a script below:



Code:
$ cat ./split_file.ksh
#!/bin/ksh
#

myPID=$$
grep -in "C:" file_to_split.txt > $myPID.tmp.00
cat $myPID.tmp.00

last_number=`tail -1 $myPID.tmp.00 | awk -F":" '{ print $1 }'`
switch=0
count=0

echo
echo "myPID = $myPID"
echo "last_number = $last_number"
echo

while read num
do
   if [[ $switch = 0 ]] ; then
      end=1
      switch=1
      continue
   else
      let count=$count+1
      start=$end
      end=`echo $num | awk -F":" '{ print $1-1 }'`
      echo "- Printing ${start} to ${end} ..."
      sed -n "${start},${end}p" file_to_split.txt > file_to_split.file.${count}.txt
      let end=$end+1

      if [[ $end = $last_number ]] ; then
         let count=$count+1
         start=$end
         echo "- Printing ${start} to the end ... "
         sed -n "${start},\$p" file_to_split.txt > file_to_split.file.${count}.txt
      fi
   fi
done < $myPID.tmp.00

rm $myPID.tmp*
echo
ls -l file_to_split.file.*txt
echo

wc -l file_to_split.txt
echo
wc -l file_to_split.file.*txt

exit 0

Sample output running the script is as below:


Code:
$ ./split_file.ksh
1:C:\Oracle\product\12.1.0\client_1_32Full\NETWORK\ADMIN\tnsnames.ora
6673:C:\Oracle\product\12.1.0\client_1_32Full\NETWORK\ADMIN\SAMPLE\tnsnames.oRA
13345:C:\Oracle\product\12.1.0\client_1_64Full\network\admin\tnsnames.ora
20017:C:\Oracle\product\12.1.0\client_1_64Full\network\admin\sample\tnsnames.oRA
26689:C:\Oracle\product\12.1.0\TNSNAMES\tnsnames.ora
33361:C:\Support\tnsnames.ora
39897:C:\Support\CHG0082341\tnsnames.ora

myPID = 26172
last_number = 39897

- Printing 1 to 6672 ...
- Printing 6673 to 13344 ...
- Printing 13345 to 20016 ...
- Printing 20017 to 26688 ...
- Printing 26689 to 33360 ...
- Printing 33361 to 39896 ...
- Printing 39897 to the end ...

   6672 file_to_split.file.2.txt
   6672 file_to_split.file.3.txt
   6672 file_to_split.file.4.txt
   6672 file_to_split.file.5.txt
   6536 file_to_split.file.6.txt
   6672 file_to_split.file.7.txt
  46568 total

Is there an awk one-liner way of achieving the same result? Smilie

Generates one hand with permutations and the tutorial for how to use them. --generate=N Generate N random boards --load=boards.txt Load boards+analysis from boards.txt --load-dds=boards.dds Load boards from boards.dds in dds format --load-analysis=tricks.txt Load analysis from tricks.txt --permutations=permutations.txt Generate the permutations and save them to the given file --curtains=curtains.txt Save curtain cards to file curtains.txt --save=boards.txt Save the boards+analysis to boards.txt --save-dds=boards.dds Save the boards to boards.dds in dds format --save-analysis=tricks.txt Save the analysis to tricks.txt --format=html|txt|pdf Set the output mode to the given format --title=title Set the title for the output --output=hands.txt Print the hands to hands.txt, rather than to standard output --stats Generate statistics about the set of boards; included in the hands output --analyze Run the dds analyzer on the boards and print the resulting numberof tricks (warning SLOW) --criteria= A list of criteria to apply to each generated hand to generate specific hand types. The list should be space separated and each item may be suffixed with a colon and a (fractional) probability value which can be used to weight the criteria.

Factor is in the range 0 to 1. On each attempt to generate a board it is rejected if it doesn't match the criteria with the given probability. A factor of about 0.8 gives roughly half matching boards AUTHOR
