I use plink.exe to automate remote commands that return data to Windows machines. This works well on newer servers running Red Hat since the commands were developed for bash and the designated user's login shell is bash. I need to also support older servers which are running Solaris 10 but the designated user's login shell is sh. I would like to use the same commands and be able to use array variables which apparently are not supported by sh. The commands are saved in a local text file and the file name is used in plink's -m option. Each command is then executed via SSH. An example of some of the file contents are below.
cd /opt/audit
tsmin=`perl -MTime::Local -le 'print timelocal(0,0,0,7,10,2017)'`
tsmax=`perl -MTime::Local -le 'print timelocal(59,59,23,7,10,2017)'`
echo "R,$tsmin,$tsmax"
filelist=`ls FaultEvent_* | nawk -F'_' '$2$3>=2017110700 && $2$3<=2017110723 {print $0}'`
nawk -F',' -v tsmin=$tsmin -v tsmax=$tsmax '$1=="A" && $2>=tsmin && $2<=tsmax {OFS=",";$3=strftime("%F %T",$2);print $0}' $filelist /dev/null | sed 's/ *, */,/g'
nawk -F',' '$9 ~ "component" {OFS=",";print "S," $0}' ObjState_20171107 /dev/null | sed 's/ *, */,/g'
filelist=`ls DomainEvent_* | nawk -F'_' '$2$3>=2017110700 && $2$3<=2017110723 {print $0}'`
nawk -F',' '$12 ~ "component" {OFS=",";$3=strftime("%F %T",$2);print $0}' $filelist /dev/null | sed 's/ *, */,/g'
I cannot figure out how to format these commands to run under a bash subshell and return stdout. I thought the following would do it but I get "undefined variable" messages and no return. I also tried other variations with similar results.
/bin/bash << eof
cd /opt/audit
tsmin=`perl -MTime::Local -le 'print timelocal(0,0,0,7,10,2017)'`
...
echo "R,$tsmin,$tsmax"
...
eof
How can I run a series of commands in a bash shell from sh login shell and return stdout. Extra credit: I also need an alternative to strftime in the nawk statements since these Solaris 10 boxes do not have this function.
