truss: script runs without, but 'sysntax err' with it ?!
When I run a script with truss it is exiting with error.
Without truss the script runs fine!

How to understand it?

I have used the truss to resolve a 'magic' disappearing, but it brings own questions.

The main problem is in a backgroun script, which on one server just disapeares, while it works perfectly on other servers with the same 'bash' version and the same shell options.

By sysadmin advise I have run it with 'truss', and it shows some sysntax error, which is not appeared if it ran without trust.

How that could be?!

Script (it is a piece just to debug it):
Code:
  #!/usr/bin/bash
echo " bash loaded "
  shopt -s expand_aliases
echo " aliases expanded "
  alias ec=/usr/bin/echo
ec " ec - is aliased "
  typeset gr=/dev/null;
ec " typeset called - first time "
  typeset i_TST=$(ec $1|grep -i "^test" &>$gr && ec 1 || ec 0)
ec " typeset set the i_TST=$i_TST "

  rm -f stop_background_relink &>$gr
ec " removed the stop_background_relink "


for ((n=0; n<10; n++)); do
  sleep 2;
  ec " next loop -- n=$n";
done

exit;

.....
.....
.. I have just figured out, that the empty line and 2 spaces are the reason for 'truss' to not load the 'bash'; so, after that it is reasonable to be not able find the 'shopt', 'alias' and 'typeset'

BUT IT IS NOT A PROBLEM WITHOUT 'truss'!!

The command I have used to run (although only 'truss' makes difference):
Code:
> dbg_bckgr.sh </dev/null 2>&1 | tee dbg_bckgr.res &

and
Code:
> truss -d dbg_bckgr.sh </dev/null 2>&1 | tee dbg_bckgr.res &

Is it the same on different servers or it is only on our ?!?
Could someone explain that, why that is happening ?!?!

Here is the log of run without the 'truss' and with it (sorry for long list, but how else?):

The script is obviously having trouble finding command when run from truss(1); typeset(1) and shopt are shell builtins so bash(1) should not need to hunt down your PATH to find them... This is typical behaviour of scripts run from cron(1m) for instance where there is no user environment for the script to run in, perhaps this is the same?

May I recommend for starters that you put a PATH= line at the start of the script directly after the shell so that you can set it to only include those directories you need to run the script? e.g.:
Code:
PATH=/usr/bin:/usr/sbin:/usr/dt/bin:/usr/openwin/bin; export PATH

As far as I can see you only need /usr/bin for echo(1) and rm(1), the former of which you have referred to fully pathed anyway and see how you get on? This will certainly shorten the truss output anyway!

Thank you, TonyFullerMalv, for your opinion and useful advise. I believe adding path should speedup performance. (Am I right?)
Althoug I believe, the problem is in not loading the 'bash' at all. The first line in 'trust' dispay the 'sh' is loaded, instead.
Code:
execve("/usr/bin/sh", 0xFFBFDEF4, 0xFFBFDF00)  argc = 2

And that is not, I guess, without the 'truss'.
That is weird.
I have try to run the script, having the '#!.." from first position (just did not include the log, as it is far mach.)
As I have said, if there is no any space on beginning, no try to search all buildin commands in all paths.

But, I will try tomorrow to define the PATH and will let to know how that will reflect the 'truss' log.
Appreciate!

This is the expected behavior. The misformed #! line is causing the exec to fail. This is covered in detail here: https://www.unix.com/tips-tutorials/3...r-bin-ksh.html
# 5  
Old 05-27-2009
Yes shortening the PATH will improve the performance.

To prove the bash theory switch to bash then run the truss which will then be running inside a bash shell.
Code:
$ bash
$ truss -d dbg_bckgr.sh </dev/null 2>&1 | tee dbg_bckgr.res &

and see if it then behaves.

If the line:
Code:
  #!/usr/bin/bash

is literal then the spaces in front of the "#" need to be removed and stating the obvious it would be good to check that is to confirm that /usr/bin/bash exists (or /bin/bash).

Perderabo, you have done great work to describe about the sharpbang '#!' !
I have read it and have some new interested points.
But,.. I see that the different systems behaives differently on white spaces before sharpbang, but how is the same system has no problem to run script (with spaces before '#!') by itself, but does not able to realise it under the 'truss' I still not clear.

TonyFullerMalv - regarding running the script under 'bash' - I use bash as my shell all the time, and provided truss-log is under bash.
(Although it is a hint how script could fail for 'production control' where the 'sh' is used..!!)

Regarding the PATH - it is turned out, that it is not usefull, as actual script use Oracle and internal system calls; so, it would required to copy almost all environment PATH..


I appreciate responces!
