remove 10 lines at header

[maxcrook]

I need to remove 10 lines at the start of a file, then remove 9 lines at the bottom of the same file.How can I do this ?

Once the header(10 lines) and footer (9 lines) have been removed i then need to append the data within that file to the end of a file before the 9 lined footer !

Hope ive made this clear.

kindive sounds like an "assignment". This will get you started.

#!/usr/bin/ksh
FILE=$1
NUM_OF_LINES=`cat $FILE | wc -l`
TAIL_NUM=`expr $NUM_OF_LINES - 10`
HEAD_NUM=`expr $TAIL_NUM - 9`
tail -$TAIL_NUM $FILE | head -$HEAD_NUM

Actually the last line of your script needs to be:

tail +11 $FILE | head -$HEAD_NUM

you see the tail +11 displays the file starting from line 11. That part is NEVER variable. Einstein47
