# Cicada is not Bash
While I built cicada to replace bash as a daily-use shell, cicada is not as
mature as bash. Some "complex" command lines may not work as expected. I
recommend that you have `bash` installed on your system too. Occasionally you
need to use bash as the receiver of a "copy-and-paste" command from the
internet.
For [example](https://www.gnu.org/software/gawk/manual/html_node/Quoting.html),
the following commands in bash will print out `single quote: <'>`.
```
$ awk 'BEGIN { print "single quote: <'"'"'>" }'
$ awk -v sq="'" 'BEGIN { print "single quote <" sq ">" }'
```
Neither of them works in current cicada.
In cicada, you should avoid complex quoting things. Instead, you can write it
like this:
```
$ awk 'BEGIN { print "single quote: <\47>" }'
```
Todo: add more examples that differ from bash.
