[SOLVED] unable to declare array in Solaris

ankitpandey · 12-27-2012, 06:50 AM

Hello Team,

While trying to declare Array in Solaris, it is throwing "declare: not found" error. Can you please suggest.

Code:

$ echo $SHELL
/bin/bash
$ declare -a vt_tbl_array
declare: not found
$

Thanks,
Ankit

Try this:

Code:

$ echo $BASH_VERSION

Code:

$ echo $BASH_VERSION

$

For my username korn shell is default, i was trying to run that on bash by keeping it on top line of script. I hope that runs it on bash irrespective of what shell is defined for me right ?

Above result gives no result.

Now is it a script, or dialogue? If script, then begin it with a she-bang:

Code:

cat test.sh
#!/bin/bash
echo $BASH_VERSION
ps
./test.sh
3.2.0(1)-release
     PID    TTY  TIME CMD
  848044  pts/3  0:00 -bash 
 1003718  pts/3  0:00 ps 
 1073356  pts/3  0:00 /bin/bash ./test.sh

Code:

$ cat test1.sh
#!/bin/bash
echo $BASH_VERSION
ps

$ sh test1.sh

   PID TTY         TIME CMD
 11741 pts/16      0:00 sh
  1751 pts/16      0:00 ksh
 11742 pts/16      0:00 ps
$

No Luck.

Be careful, the following commands are different:

Code:

1: sh test1.sh
2: ./test1.sh # don't forget chmod +x test1.sh beforehand

You should try the second one. Also check where is your bash actually is: command which bash

Thanks, i missed that.

Code:

$./test1.sh
3.00.16(1)-release
   PID TTY         TIME CMD
 17726 pts/16      0:00 test1.sh
  1751 pts/16      0:00 ksh
 17727 pts/16      0:00 ps

$ which bash    
/usr/bin/bash

It's Working !!... and it has resolved the problem... i was running it as sh <script_name>.sh, but when i ran it as ./<script_name>.sh it worked.

Can you please explain why it is differnt and how can i test it manually ? By this was i can only test in by putting this in script, i was trying to test each line by line, but that takes the default shell. Korn shell dosen't support array ?

Thanks

"sh scriptfile" means: dear sh, execute this script; while "./scriptfile" means: dear kernel, find out (from the first line) what program interprets this scripts, then start that interpreter (bash, in this case, but could have been anything else like perl, php, python etc), and give it 'scriptfile' as parameter -- the the interpreter opens, reads and executes 'scriptfile'.

Thanks NavemTeve.. for this clarification.

Notice too that the first line of the shebang is "#", which means that when you give the file to a shell as an argument, it will be ignored as a comment.

The shebang only has special meaning when the file is executed directly, as explained above.
