RunsArray just comes up as an empty array. Any ideas?

What is the output of:
Code:
sed -n '/set Runs/{s/.*(//; s/)$//p}' SortScans

What is the format of SortScans?

sed -n '
/set Runs/ {
    s/.*(//;
    s/)$//p

This does don' t print any line by default (-n).
For any line that contains "set Runs":
  • Replace everything up to last ( with nothing
  • Replace ) on end of line with nothing and then print result

Thanks Chubler,

I was closeSmilie. My original code, this time a working code is:
Code:
RunsArray=( $(awk -F"(" '/set Runs/{sub(/\)/,"");print $2}' SortScans) )
FoldersArray=( $(awk -F"(" '/set Folders/{sub(/\)/,"");print $2}' SortScans) )

echo  ${RunsArray[@]}
echo  ${FoldersArray[@]}

And compressed changing field separator with your suggestion is a you said before:
Code:
RunsArray=( $(awk -F"[)(]" '/set Runs/{print $2}' SortScans) )
FoldersArray=( $(awk -F"[)(]" '/set Folders/{print $2}' SortScans) )

echo  ${RunsArray[@]}
2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
echo  ${FoldersArray[@]}
anat RS1 RS2 RS3 DTI DTI DTI DTI DTI DTI DFM DFM


Thanks for your correction!Smilie
