bash

Hello,

I'm trying to write a bash one liner that finds some files, and for each file it appends a string to the end of them. I tried several attempts with no luck.

Code:

find . -name "*.txt" -exec echo "append_this_string" >> `echo {}` \;

OR

Code:

find . -name "*.txt" -exec echo "append_this_string" >> {} \;

Both the these examples do not work. I tried googling and reading man pages, but couldn't find anything. Since my bash skills aren't very good, I was hoping someone could help me out.

I figured I could write a script, but I was hoping I could do it with a simple one-liner. (to impress the ladies

)

Thanks,

Here's my one-liner:

find . -name "*.txt" | while read TXT ; do echo "string to append" >> $TXT ; done

Using sed:

Code:

find . -name "*.txt" -exec sed -i '$ a\append_this_string' {} \;

Edit: sorry for double post, just a mistake...
