I have an output: <pre class="prettyprint"><code>-- out1 -- out2 -- out3 </code></pre> I want to get the output: <pre class="prettyprint"><code>out1 out2 out3 </code></pre> I thought of using: <pre class="prettyprint"><code>tr '--' '' </code></pre> but it doesn't recognize '--' to be the first string I want to substitute. How do I solve this?

How do I use tr to substitute '--' string

I have an output:

--
out1
--
out2
--
out3

I want to get the output:

out1
out2
out3

I thought of using:

tr '--' ''

but it doesn't recognize '--' to be the first string I want to substitute. How do I solve this?

cat file | sed '/^--/d'
