This look a little like a shell script, in which case i would say that you finish an if...then... whith a fi but your condition for the if needs to be fixed somewhat.

What does esxcli software vib list | grep -i net-mst give you?

Would the output from esxcli software vib list | grep -ic net-mst be better or perhaps you just need to test the return code of esxcli software vib list | grep -qi net-mst where zero is successful match and 1 is a failure to match. Return code 2 is an error.

I'm not sure that the trailing & will be useful either. It will put that command into the background, so you don't know (without looking) when it has finished.

Do these suggestions/questions help?

very nice.

yes esxcli software vib list | grep -ic net-mst

does give an output of 1 when available

how do I put that together in bash?

So your script might start:-

#!/bin/bash

echo "$(date) : This is the start"

if [ $(esxcli software vib list | grep -ic net-mst) -eq 1 ]
then
   echo "$(date) : Software found"
   esxcli software vib remove -n net-mst
   esxcli software profile update -d /vmfs/volumes/deport.zip -p profile
   run /tmp/upgrade.sh
else
   echo "$(date) : Software not found"
fi

echo "$(date) : This is the end"

Obviously completely untested and I'm guessing at what you actually might be trying to do.

Does that help? If the condition matches, it runs the next three statements after the then in sequence until the else statement. Failing the test means it runs the echo statement. Either way, the control continues after the fi

ok trying to do more modifuications

I need another check

esxcli hardware platform get | grep -i Product

output is like this

Product Name: Proliant BL460c Gen8

or could be

Product NAme: Proliant BL460c Gen9

But it could be Gen7 or

I need a check that if its Gen9

then

do

esxcli software profile update -d "/vmfs/volumes/vol1/depot1.zip" -p depot

or if its not Gen9

or if its Gen8 or Gen7

do

esxcli software profile update -d "/vmfs/volumes/vol1/depot2.zip" -p depot2

any idea?

You could try this:

#!/bin/bash

echo "$(date) : This is the start"

if [ $(.esxcli software vib list | grep -ic net-mst) -eq 1 ]
then
   echo "$(date) : Software found"
   esxcli software vib remove -n net-mst
   PN=$(esxcli hardware platform get | grep -i Product)
   case $PN in
      *Gen9)
           echo "$(date) : Gen 9 detected"
           esxcli software profile update -d /vmfs/volumes/vo1/depot1.zip -p depot
           cp -R /vmfs/volumes/volname/dirname /tmp
           chmod +x /tmp/dirname/update.sh
           run /tmp/upgrade.sh &
      ;;
      *Gen[78])
           echo "$(date) : Gen 7/8 detected"
           esxcli software profile update -d /vmfs/volumes/vo1/depot2.zip -p depot2
       ;;
       *)
           echo "$(date) : unknown version: $PN"
       ;;
    esac

else
   echo "$(date) : Software not found"
fi
