I have some files created by a process in UNIX. I wanted to do some file processing:

1. I want to append a string "EOF" as the first word on the last line of all the files except the last file.

2.Similarly, I want to append "BOF" string as the first word to all the files except the first file, also this "BOF" string should be repeated for lines, till it find a line <abcd>.

Thanks for ur time!

Try this...But this may not be the quickest way to do this..

for i in $(ls * |sed -n '1!p'| sed -n '$!p')
do
[[ -f "$i" ]] && { echo "BOF$(cat $i)" > $i; echo "$(cat $i)EOF" >$i; }
done

echo "BOF$(ls *|sed -n '1p;')" >$(ls *|sed -n '1p;')
echo "$(ls *|sed -n '$p;')EOF" >$(ls *|sed -n '$p;')

Try this...But this may not be the quickest way to do this..Also,I assume that all the files in the current directory requires this update


for i in $(ls * |sed -n '1!p'| sed -n '$!p')
do
[[ -f "$i" ]] && { echo "BOF$(cat $i)" > $i; echo "$(cat $i)EOF" >$i; }
done

echo "BOF$(ls *|sed -n '1p;')" >$(ls *|sed -n '1p;')
echo "$(ls *|sed -n '$p;')EOF" >$(ls *|sed -n '$p;')
