[comp.unix.questions] sed/grep problems

claus@iesd.auc.dk (Claus S. Jensen) (02/13/91)

  I'm looking for a way to do some things concerning the tab-symbol.

1) I would like to find occurences of tab (\t) in a file.
   grep "\t" <file> doesn't work.

2) And I would like to use sed to replace these tabs with
   spaces.
   sed -e "s/\t/   /g" <file> doesn't work.


  If anybody know anything about this please answer the questions.

Use the <tab> instead of \t.
But... if it doesn't accept the <tab>, you have to write a file with:
	 sed 's/	/bla/g' < $1 > $1.bla
It's tested on SVR3.2
