Hello,

this is because $PWD gets expanded by shell before sed gets called, so what
actually gets executed is:

sed s/bbb.*/bbbb:/home/myself/ text.txt

...which is obviously syntactically incorrect.

To get result you want, try using different separator character than /, for
example the comma, or underscore:

$ sed s,bbb.*,bbbb:$PWD, text.txt
$ sed s_bbb.*_bbbb:$PWD_ text.txt
