Bash – find greatest last-modified files of /dirA/file, /dirB/file

bash

Suppose we have two directories, dirA, dirB, which the exact same PDF files, just different last modified.

What is a bash script (no awk) that can search through each file name (assume always in both dirA, dirB) and for each filename, outputs which of the files (dirA/file or dirB/file) has the greater last-modified; file-modified-last?
e.g.

if dirA/file.lastmodified > dirB/file.lastmodified 
##take action

Best Answer

With GNU stat:

shopt -s dotglob

for file in dirA/*; do
    [[ -f "dirB/${file##*/}" ]] || continue
    if (( "$(stat -c %Y "$file")" > "$(stat -c %Y "dirB/${file##*/}")" )); then
        # take action
    fi
done

Bash – Remove all files except for last file of each month

With the file zz containing the list of file names, this works, so just replace cat zz.

cat zz | grep -vF -f <(cat zz|sort -r|uniq -w11)

e.g. echo *.sql | grep -vF -f <( echo *.sql | sort -r | uniq -w11 ) | xargs rm

As is, it won't work if spaces in file names, and very fragile to filename length.

Bash – Delete .pdf files only if .xlsx files in directory have same filename

Loop over the pdf files, use parameter expansion to extract the basename:

#!/bin/bash
for pdf in *.pdf ; do
    basename=${pdf%.pdf}
    if [[ -f $basename.xls || -f $basename.xlsx ]] ; then
        rm "$pdf"
    fi
done

Update: I got the logic backwards, should be fixed now.
