using perl on the command line, like sed or awk

[gorda]

Hello,

Using sed or awk, I can quickly parse and perform operations on the
command line itself as in:

cat file | sed 's/cat/dog'
cat file | awk ' /cat/ {print "found the cat"} '

How can i do something like the above in perl on the command line
without having to write a script in a seperate file?

Thanks
