Control Characters
Hallo Team,

I am trying to get rid of the dollar sign. I managed to remove all the other special characters but i am struggling with this one.

Code:
-bash-3.2$ cat -e missing_revenue_20141112.csv|less|head
BW0522168531211141180935668@196.23.110.141$

-bash-3.2$

Please assist.

Code:
man cat

tells me that -e adds a $ at the line end (so you could see trailing space characters).
While -v shows the special characters and no $ line ends.

I suppose you could try:

Code:
 
cat missing_revenue_20141112.csv | tr -d '\n'

however, I doubt that'll have the effect your expecting Smilie

hint: read the man page MadeInGermany provided Smilie

Basic longhand example, OSX 10.7.5, default bash terminal.
This has its limitations but is simple and a starting point.
