How to get the number of files in a folder as a variable?
- by Jason
Using bash, how can one get the number of files in a folder, excluding directories from a shell script without the interpreter complaining?
With the help of a friend, I've tried
$files=$(find ../ -maxdepth 1 -type f | sort -n)
$num=$("ls -l" | "grep ^-" | "wc -l")
which returns from the command line:
../1-prefix_blended_fused.jpg: No such file or directory
ls -l : command not found
grep ^-: command not found
wc -l: command not found
respectively. These commands work on the command line, but NOT with a bash script.
Given a file filled with image files formatted like 1-pano.jpg, I want to grab all the images in the directory to get the largest numbered file to tack onto the next image being processed.
Why the discrepancy?
