#!/bin/sh - does not help
Hi,
I am using bash shell and have a simple shell script (test.sh) as given below,
#!/bin/sh
echo "testing..."
Here, when I execute the script like below, it works well.
cmd -> sh test.sh
testing...
I have seen, these files can be executed, simply by using the file name directly, like given below. But, in my case it gives "command not found" error.
cmd -> test.sh
-bash: test.sh: command not found
In the first line of the script, I have given as "#!/bin/sh", hence to my knowledge, it should run prefix /bin/sh command automatically and invoke as given below,
/bin/sh test.sh
Alternatively, in the first line, I also tried using "#!/bin/bash", still get the same error. What is the mistake I am making

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.
