script for inserting form feeds into file

[james gould]

Need to write a script that will insert
form feed every 36 lines. Any suggestions?

Hi,

Did you look at the command pr?. Look at it's man page.

as in "pr -l36" where "-l36" is "dash el (lower case L) 36".

Hi James,

The following will insert a FF after every 36 lines of the input file. The FF will be the first character of each line following the 36th line. If you want it to be on a line by itself, change the echo to: echo "\013" (leave off the \c")

# Begin script
ctr=0
while read line
do
echo $line
ctr=`expr $ctr + 1`
if [ $ctr -eq 36 ]
then
echo "\013\c"
ctr=0
fi
done out

I'm sorry, I misread the ascii table. Please change 013 in my answer to 014.

Thanks,
Darrell
