Shell Programming and Scripting

Hi ctsgnb,

If there a way that we can append a temporary string to the newly created files. So that we will be able to differentiate between the original file. So this will work fine, even without knowing about total number of files generated.

Yes :

Code:

echo "temporary string" >> newly_created_file

Code:

for i in origfile.*
do
echo "temporary string" >> $i
done

sorry for the copy/paste snafu:

Code:

nawk 'NR%10000==1 && ++c{close(f);f=FILENAME "."c}{print $0 > f }END{print "created " c " files"}' myFile

...borrowed from versh99

just putting the line number into a variable

Code:

maxline=10000
awk -vm="$maxline" 'NR%m==1 && ++c{close(f);f=FILENAME "."c}{print $0 > f }END{print "created " c " files"}' yourfile.txt

I also think that split might be the best option.

If you create a temporary directory and make that the current location, you could then use things like:-If the creted filenames are awkward, you can use options in split to set the beggining and ending of the filename to suit better. Check your manual pages to get your OS specific flags to use.

You can fairly easily then read around them. If you were looking for a specific line number, then the sed to get a specific line reference by variable $line is:

Code:

sed -n ${line}p $filename

The p is required, but is not part of the variable, hence the {} to clearly identify it.



i hope that this helps.
