POthis BASH code works on a command line, but not when i move it into a script
text
Body
copied!<p>I built-up a kludgey script on the CLI that I can't successfully move into a text file. <strong>I know it's poorly-written, but I'm interested in resolving the problem I'm having, not re-writing it.</strong> I want to understand why my poorly-written code behaves differently when executed on the command line compared to when it's saved as a file.</p> <p>I think it's related to something getting interpolated prematurely in the script, because if I substitute the one-liner version into the same file (without formatting) I get identical output. Note the debug line below and how it doesn't print.</p> <p><strong>CONTENTS OF SCRIPT</strong></p> <pre> #!/bin/bash totalNodes=0 #initialize sum echo -e "ID\t\t\tNODES"; #title line for n2 in $( #n2 will get populated with the number of nodes (to be added to totalNodes) for n in $( #n is an intermediate string that munges the Resource_list.nodes line (kludgy) for i in $( qstat|grep " ef "|cut -f 1 -d ' ') #i gets the ef queue lines do echo "debug $i" j=$(echo $i|sed 's/(\d+)\..+/\$1/'); #j is the actual ID qstat -f | grep -A43 $j; #extracts the full output from qstat for this job ID done|grep Resource_List.nodes) #closes definition of n over loop do echo ${n};done|grep ppn) #closes definition of n2 over loop do echo "$j ${n2:0:1}" #output line totalNodes=$(($totalNodes+${n2:0:1})) #counting nodes done echo "$totalNodes nodes of 16 running in EF queue" </pre> <p><strong>EXPECTED OUTPUT</strong> (what I get at the command line):</p> <pre> ID NODES 2378512.yaddayadday-adm 4 2378512.yaddayadday-adm 4 2378512.yaddayadday-adm 4 2378512.yaddayadday-adm 2 14 nodes of 16 running in EF queue </pre> <p><strong>CURRENT OUTPUT</strong> from the script</p> <pre> ID NODES 4 4 4 2 14 nodes of 16 running in EF queue </pre> <p>So I'm confused how I can get the right total (meaning $n2 is getting defined correctly) but I can't even print $i on the debug-with-print line (line 8.)</p> <p>For reference, here's the one-liner. Like I said, <strong>this gives the "EXPECTED OUTPUT" shown above, when executed on the command line, but the same output as the above codeblock "CONTENTS OF SCRIPT" when I save it as a file with no additional formatting.</strong></p> <pre> totalNodes=0;echo -e "ID\t\t\tNODES";for n2 in $(for n in $(for i in $(qstat|grep " ef "|cut -f 1 -d ' ');do j=$(echo $i|sed 's/(\d+)\..+/$1/');qstat -f | grep -A43 $j;done|grep Resource_List.nodes);do echo ${n};done|grep ppn);do echo "$j ${n2:0:1}";totalNodes=$(($totalNodes+${n2:0:1})); done;echo "$totalNodes nodes of 16 running in EF queue" </pre>
