How to remove string between two chracters and before the first occurance using sed

I would like to remove the string between ":" and the first "|" using sed.

input:
|abc:1.2.3|def|

output from sed:
|abc|def|

I managed to come up with sed 's|\(:\)[^|]*|\1|', but this sed command does not remove the first character (":"). How can I modify this command to also remove the colon?

>Solution :

You don’t need to group : in your pattern and use it in substitution.

You should keep it simple:

s='|abc:1.2.3|def|'
sed 's/:[^|]*//' <<< "$s"

|abc|def|

: matches a colon and [^|]* matches 0 or more non-pipe characters
