Question

I am using grep -A command to get a specific pattern. It gives -- at the end of every block, how I can remove these dashes?

Accepted Answer

AFAIK it's not mentioned in the man page, but in the Context Line Control section of info grep you will find the option

‘--no-group-separator’
     When ‘-A’, ‘-B’ or ‘-C’ are in use, do not print a separator
     between groups of lines.

Answer 2

You have at least three alternatives:

With -v option (works on any version of grep):
```
... | grep -A1 "pattern" | grep -v -- "^--$"
```
Also, | sed '/^--$/d'.

With undocumented --group-separator

... | grep -A1 "pattern" --group-separator ""

With --no-group-separator (as mentioned steeldriver).
```
... | grep -A1 "pattern" --no-group-separator
```
