sed syntax question

[cpnhowdy]

Ive got a table of number like so:
23/34/45
55/76/44
etc.
and I want to replace every / with a colon : . Im getting syntax errors when trying to pass the "/" symbol to sed to be replaced by ":".
It should be obvious but it escapes me..

If you are using the standard forward slash delimiter, then you'll have to escape the slash you want to replace by preceding it with a backslash. Alternatively you could just use a different delimiter.

try:

sed -i "s,/,:,g" yourfile.txt
