In my bash script I want to say "if argument 2 is anything except x, y or z, than echo this" (x y and z being words).
So my script looks like this:
This usually works but than I also want to say "if argument 2 IS x, y, or z, but argument 4 is not one of them, echo 'unrecognized input: $4'". So how to I format this so my script does both. I had this, but whenever argument 2 was x, y or z, and argument 4 wasn't, I still got the "unrecognized input: $2" error message.
how can i create a script with a correct control flow/loop(?) to
provide output from 3 files?
file1
one
two
three
file2
yellow
red
orange
file3
banana
apples
cantaloupes
output file:

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
