perl/sed -i removes link
hello,
is it a behavior of
or
that "-i" removes unix link .
example :
i create a file "src_file" and link it to "link_file" and then i start "perl -i"
Quote:
echo "AAA" > src_file
ln -s src_file link_file
ll
lrwxr-x--- 1 user root 8 May 8 14:20 link_file -> src_file
-rw-r----- 1 user root 4 May 8 14:20 src_file
perl -i -pne 's/AAA/BBB/g' link_file
ll
-rw-r----- 1 user root 4 May 8 14:21 link_file
-rw-r----- 1 user root 4 May 8 14:20 src_file
cat link_file
BBB
the link is removed. does another option exists to change content of a file without temporary files ?
UNIX-Version:
HP-UX and i also tested it with
Linux
regards
