Is there any comprehensive list of characters that need to be escaped in Bash? Can it be checked just with sed?
In particular, I was checking whether % needs to be escaped or not. I tried
echo "h%h" | sed 's/%/i/g'
and worked fine, without escaping %. Does it mean % does not need to be escaped? Was this a good way to check the necessity?
And more general: are they the same characters to escape in shell and bash?
