Please state what shell you are using?
Quote:
sh testscript.sh ' ls -t Appl*and*abc* | head -n 1'
This will list one file name as ana argument..
It won't. The single quotes '' will stop execution of the "ls" command line and pass the whole "ls" command line intact as a parameter to testscript.sh.
What is the contents of "testscript.sh"? Does it contain an "eval" command?
I think we need to know in words what you are trying to achieve?
Consider what input you will provide, what processing is required, and what output you expect.

Hi all,
I'm new to Shell scripting. In my shell script for Bourne shell, the script accepts a date parameter which is optional. If the value is supplied, the supplied value should be assigned to a variable. If not, the current date will be assigned to the variable. My script is like this.

Hi,
Lets say I have a script "ss" which does this
read abc
echo $abc
read pqr
echo $pqr
Now if I want to pass and argument to only "abc" how do I do it.
If I do
echo "somevalue" | ss, it does not prompt for pqr and its value comes out as blank.
Any help is appreciated
Thanks

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.
