Shell Programming and Scripting

Hi,

Why does this piece of script work on a Solaris 10 test.sh script but if I include it in the request script of packaging generates errors?

Code:

        
until [ -n "$CONFIGCACHE" ] && [ -n "$prompt" ] && [ -z `echo $CONFIGCACHE | /usr/xpg4/bin/sed -e 's/[YN]//g' ` ]
        do
                echo -n "Do you want to configure Cache Manager? [Y/N] "
                read -e -n 1 CONFIGCACHE
                echo ""
                prompt=1
        done

In the request script it stops at read -e:
-n Do you want to configure Cache Manager? [Y/N]
/var/tmp//installe5aOBQ/checkinstallh5aOBQ: -e: is not an identifier
pkgadd: ERROR: request script did not complete successfully


If I replace "read -e -n 1" with simple read I get
/var/tmp//install0UaOMQ/checkinstall3UaOMQ: test: argument expected
pkgadd: ERROR: request script did not complete successfully


Thanks,
Bianca

For this I get

Do you want to configure Cache Manager? [Y/N] /var/tmp//installltaiLW/checkinstallotaiLW: -sn1: is not an identifier
pkgadd: ERROR: request script did not complete successfully

Why don't the read parameters work properly ? I have same with read -e , read -n 1, etc.

You must run it with bash; no other shell will work for that code.

I set #!/bin/bash in the scripts.

In a separate script it works .. and in the request script doesn't work that's why is so frustrating.

What command line do you use to run it?

And please post the entire script that contains it.

And post the output of:

Code:

/bin/bash --version

Hi

bash-3.00# /bin/bash --version
GNU bash, version 3.00.16(1)-release (sparc-sun-solaris2.10)
Copyright (C) 2004 Free Software Foundation, Inc.
bash-3.00# /usr/bin/bash --version
GNU bash, version 3.00.16(1)-release (sparc-sun-solaris2.10)

In the scripts I use #!/bin/bash

The request script I use in the package is pretty long. I refer only to this section as it is not related to nothing before.

So if I run it separate it works.

If I run it in the request script:
1. I have to delete read parameters -e -n 1 as they generate errors
2. Then I get
/var/tmp//install59a41W/checkinstall89a41W: test: argument expected
pkgadd: ERROR: request script did not complete successfully



bash-3.00# cat test.sh
#!/bin/bash

until [ -n "$CONFIGCACHE" ] && [ -n "$prompt" ] && [ -z `echo $CONFIGCACHE | sed -e 's/[YN]//g' ` ]
do
echo -n "Do you want to configure Cache Manager? [Y/N] "
read -e -n 1 CONFIGCACHE
echo ""
prompt=1
done

bash-3.00# ./test.sh
Do you want to configure Cache Manager? [Y/N] Y

bash-3.00#

Thanks,
Bianca
