something like  shell(wc -l "filename")  

Info in man pages for cli programm with name 'wc'

wc

-c, --bytes
 print the byte counts 

-m, --chars
 print the character counts 

-l, --lines
 print the newline counts 

--files0-from=F
 read input from the files specified by NUL-terminated names in file F 

-L, --max-line-length
 print the length of the longest line 

-w, --words
 print the word counts
