[[:: not found in bash

Question

I get the following errors with my bash script.

ncompile.sh: 1: ncompile.sh: ###: not found
ncompile.sh: 52: ncompile.sh: [[: not found
Chose your Operating System. {Supported OS: Debian, Ubuntu, Fedora, CentOS, FreeBSD}
Debian
ncompile.sh: 61: ncompile.sh: [[: not found
ncompile.sh: 61: ncompile.sh: [[: not found
ncompile.sh: 70: ncompile.sh: [[: not found
ncompile.sh: 70: ncompile.sh: [[: not found
ncompile.sh: 79: ncompile.sh: [[: not found

With this script:

Are you sure your script is launched with bash ? Basic shell doesn't have `[[` only `[`. — Zulu, Jan 07 '14 at 21:59
@Zulu I was running "sh myscript.sh" now I did "bash myscript.sh" and it worked. — dominique120, Jan 07 '14 at 22:06
@Paul R when I use the shebang I get an error related to a missing directory. — dominique120, Jan 07 '14 at 22:06

You should begin by insert bash she-bang at first line:

#!/bin/bash

I think your script basically uses sh. shell only support simple bracket ([).

When I add that I get this: ./ncompile.sh: line 1: #!/bin/bash: No such file or directory – dominique120 Jan 07 '14 at 22:30

@user3084450, you add the shebang line, and then make your script executable with `chmod a+x ./ncompile.sh`. You can the execute it without having to specify "sh" or "bash" : `./nocompile.sh` – glenn jackman Jan 07 '14 at 22:37
@Zulu I think you wanted to write *shell __only__ supports simple bracket (`[`)* – whoan Oct 21 '14 at 00:13

the variable ans1_1 does not read, you must "read ans1_1" before using it
