So now i have a need to insert ' at the beginning of text and at the

../../wp-blog-header.php and the finished text should look like
'../../wp-blog-header.php'. How would i make a bash script to
accomplish this or is it possible?
For 2000 files the limit of the `*' expansion could be reached.
Therefore you may use `find' together with a shell loop and
the `ed' ... e.g.
find / -name '*.php' | \
while read php; do
ed $php &> /dev/null <<-EOF
1
,s/.*/'&'/
.
w
q
EOF
# ^^^ this is a <TAB>!
done
if you want to use shell special signs literal like `$' in
your text you may use `"EOF"' instead of `EOF'. Please
note that if you're using a `-' before the `EOF' or before
`"EOF"' you are able to indent the second `EOF'/`"EOF"' with
a tabulator sign. If the `-' is missed the `EOF'/`"EOF"' has
to be placed at the very first beginning of the line.
An other editor is the sed, with its inplace option `-i':
find / -name '*.php' | \
while read php; do
sed -ri "1,1 s/.*/'&'/" $php
done
it is a bit shorter ... but ed is in some cases more
powerfull. Nevertheless both editors allow to use
other boundary characters as the `/' ... sometimes
I use `s@old@new@' or `s!old!new!'.
