Error using sed.

Expand Post »
I am trying to delete any line of text that contains "$npname" and the word "in." The script works if $npname is only one word, but if it is more than one work I get "error: unterminated address regex" How can I fix this?

Shell Scripting Syntax (Toggle Plain Text)
  1. sed '/'$npname'.*in/d' parts.txt > parts.tmp

Re: Error using sed.
Why not use grep ?
Shell Scripting Syntax (Toggle Plain Text)
  1. sk@svn:/tmp/daniweb$ npname="part"
  2. sk@svn:/tmp/daniweb$ egrep -vi ".*${npname}.*in.*" parts.txt
  3. sk@svn:/tmp/daniweb$ npname="part part"
  4. sk@svn:/tmp/daniweb$ egrep -vi ".*${npname}.*in.*" parts.txt
  5. part1.in
  6. part3.in
  7. sk@svn:/tmp/daniweb$ cat parts.txt
  8. part1.in
  9. part part.in
  10. part3.in

It makes a difference the quotation scheme.
sed "/$npname.*in/d" parts.txt > parts.tmp

After trying everything I could think of I finally came up with this which finally worked.

  1. sed '/'"$npname".*in'/d' parts.txt > parts.tmp

Re: Error using sed.

Re: Error using sed.
Similar but not exactly the same. I had to move the double quotes inside, and add two sets of single quotes. Thanks for the help!
