help on script execution
Hi,

Please help me on the below code of line of what it actually does

${Script_dir}/scrip1.sh &
export script1_pid=$!

${Scipt_dir}/script2.sh &
export script2_pid=$!

${Scrip_dIR}/script3.sh &
export script3_pid=$!

wait ${script1_pid} //could u tell me wht this statement isexport script1_rc=$?

wait ${script2_pid} // all these wait statements execute sequentially or parllel
export script2_rc=$?

wait ${script3_pid}
export script3_rc=$?

if [ ${script1_rc} -ne 0 ]; then
echo script 1 load has errors.
exit 1

elif [ ${script2_rc} -ne 0 ]; then
echo script2 load for has errors.
exit 1

elif [ ${script3_rc} -ne 0 ]; then
echo script3 load has errors. $
exit 1
fi




Here if the first script1 fails then the rest of wait commnads will not be executed. Is there any way to let all the other things also execute if script 1 fails. I mean to say that is there any way that wait statements execute parllely ie wait for that particular pids parllely.

parse_dynamic_clustertoc

parse_dynamic_clustertoc(1M)                              System Administration Commands                              parse_dynamic_clustertoc(1M)

NAME

       parse_dynamic_clustertoc - parse clustertoc file based on dynamic entries

SYNOPSIS

       cdrom/export/exec/sparc.Solaris_2.x/sbin/install.d/parse_dynamic_clustertoc

       cdrom/export/exec/i386.Solaris_2.x/sbin/install.d/parse_dynamic_clustertoc

DESCRIPTION

       This script parses the  clustertoc file before the suninstall(1M) process is run.  parse_dynamic_clustertoc is called by a modified syscon-
       fig script on the install CD.  When parse_dynamic_clustertoc runs, it reads the clustertoc and when it encounters SUNW_CSRMBRIFF lines,  it
       either  checks  the  platform  using the script's builtin function, or calls an external script.  The script exits with  a 0 if the cluster
       entry is included,  otherwise it will be ignored.  If the cluster entry is to be included, the SUNW_CSRMBRIFF =(test test_arg)cluster  line
       is converted to SUNW_CSRMEMBER =cluster.

EXAMPLES

       Example 1: Checking For an SX Framebuffer

       The  following is an example of a simple external test to check for an SX Framebuffer.  The entry in the  clustertoc file is shown and fol-
       lowing that is the script that must be placed in the  install.d/dynamic_test directory.

       SUNW_CSRMBRIFF=(smcc.dctoc sx)SUNWCsx
       #! /bin/sh
       #
       # Likewise, this file is expected to live under $(TESTDIR).
       #
       case "$1"
       in
               sx)     prtconf -p  | grep 'SUNW,sx' 1> /dev/null;;
