Fish Shell Loop Counter

I'm trying to count pages of PDF documents in a directory - which works fine except I cannot get the counter variable to increase. In the directory are two documents with 1 Page and 4 Pages. The return of my below script is:

1 
4

why isn't it incrementing $i ?

#!/usr/local/bin/fish


set i 0

for pdf in *.pdf
     set i (math i + (pdfinfo $pdf | grep Pages | awk '{print $2}'))    
     echo $i
end
Solution

  • Found the issue at hand - whitespace made it problematic...

    By doing **.pdf it gets recursive through all folders...

    #!/usr/local/bin/fish


set i 0

for pdf in **.pdf
     set i (math $i+(pdfinfo $pdf | grep Pages | awk '{print $2}')) 
     echo $i
 end
