i have a requirement to remove a string in a file and add "@" to the end of file. i wrote a script for this. the script is shown below.

the string value gets replaced, but the ONLY problem is that the last line in the original file gets removed and i do get the "@" at the end of file.

find . -type f -name '*.txt' -print | while read i
do
sed -e 's/TEST.//g' $i > $i.tmp && mv $i.tmp $i
echo "@" >> $i
done

can anyone let me know whats going wrong here.

can you either include the contents of one of these files or show me what the last line looks like

Your last line probably doesn't have a newline and is ignored by sed
e.g.
printf "zozo\nxoxo" | sed 's/o/0/g'
z0z0

printf "zozo\nxoxo\n" | sed 's/o/0/g'
z0z0
x0x0

contents of my file are like this:

p1: begin

abcd temp.part
xyz

end p1

I want to replace "temp." to "", this works. Also, the file should have "@" as the last line in the file;

for example the output should be:


p1: begin

abcd part
xyz

end p1
@

right now what i get is

p1: begin

abcd part
xyz
@

the line "END P1" is totally removed. how do i add the "@" to the end of file without having "END P1" removed from the file.

find . -type f -name '*.txt' -print | while read i
do
(cat $i;printf "\n@\n") | sed -e 's/TEST.//g' > $i.tmp && mv $i.tmp $i
done

That worked great.

Thanks!

it looks like 'read' was your problem there
