How to call ksh script within bash script?

  • 772

I am have written a script which will silently installed Microstrategy on Amazon Linux 2.0

In My main script i am calling Microstrategy installation script which is in /bin/ksh and mine is in /bin/bash

mstr_install.sh is as follows:

#!/bin/bash
#DATE 22-FEB-2019
#DISCRIPTION: IT will Install MSTR-11.1 with Silent Options using optins.txt file
DATE=$(date +"%Y-%m-%d_%T")
PATH="/app/soft/Installations/QueryReportingAnalysis_Linux/"

/usr/bin/mv "$PATH"options.txt "$PATH"options_backup."$DATE"
/usr/bin/cp /app/automation/mstr/options.txt  "$PATH"
/usr/bin/chmod 777 "$PATH"options.txt

cd "$PATH"

bash setup.sh -silent -options options.txt 

exit

and setup.sh is vendor script which shebang line is 

 #/bin/ksh

I am running my script like below:

#sh -x mstr_install.sh

and getting the below errors:

[root@a1-m022mstiap01 mstr]# sh -x mstr_install.sh
++ date +%Y-%m-%d_%T
+ DATE=2019-07-25_07:59:35
+ PATH=/app/soft/Installations/QueryReportingAnalysis_Linux/
+ /usr/bin/mv /app/soft/Installations/QueryReportingAnalysis_Linux/options.txt /app/soft/Installations/QueryReportingAnalysis_Linux/options_backup.2019-07-25_07:59:35
+ /usr/bin/cp /app/automation/mstr/options.txt /app/soft/Installations/QueryReportingAnalysis_Linux/
+ /usr/bin/chmod 777 /app/soft/Installations/QueryReportingAnalysis_Linux/options.txt
+ cd /app/soft/Installations/QueryReportingAnalysis_Linux/
+ /usr/bin/ksh ./setup.sh -silent -options options.txt
./setup.sh[879]: basename: not found [No such file or directory]
./setup.sh[882]: dirname: not found [No such file or directory]
./setup.sh[883]: cd: bad directory
./setup.sh[408]: uname: not found [No such file or directory]
Checking for running instances..../setup.sh[866]: ps: not found [No such file or directory]
../setup.sh[82]: cat: not found [No such file or directory]
...done.
./setup.sh[466]: mkdir: not found [No such file or directory]
Unable to check the Kernel size
+ exit
[root@a1-m022mstiap01 mstr]#

It very wired issue let me know if anything missed to mention.

Thanks Santosh G.

  1. This is wrong: 

    bash setup.sh -silent -options options.txt

    By using "bash" to start the script you skip the she-bang.

    I would assume you need to do this: 

    ./setup.sh -silent -options options.txt

    (with the executable bit set) or 

    ksh setup.sh -silent -options options.txt

    ===

    This is bad behaviour:

     PATH="/app/soft/Installations/QueryReportingAnalysis_Linux/"

    I would use a specific variable name for this that is not the same as an environment variable. Doing it like that will come back to bite you.
