Print a file's last modified date in Bash

Question

I can\'t seem to find how to print out the date of a file. I\'m so far able to print out all the files in a directory, but I need to print out the dates with it.

Answer 1

Isn't the 'date' command much simpler? No need for awk, stat, etc.

date -r <filename>

Also, consider looking at the man page for date formatting; for example with common date and time format:

date -r <filename> "+%m-%d-%Y %H:%M:%S"

Answer 2

EDITED: turns out that I had forgotten the quotes needed for $entry in order to print correctly and not give the "no such file or directory" error. Thank you all so much for helping me!

Here is my final code:

    echo "Please type in the directory you want all the files to be listed with last modified dates" #bash can't find file creation dates

read directory

for entry in "$directory"/*

do
modDate=$(stat -c %y "$entry") #%y = last modified. Qoutes are needed otherwise spaces in file name with give error of "no such file"
modDate=${modDate%% *} #%% takes off everything off the string after the date to make it look pretty
echo $entry:$modDate

Prints out like this:

Answer 3

Adding to @StevePenny answer, you might want to cut the not-so-human-readable part:

stat -c%y Localizable.strings | cut -d'.' -f1

Answer 4

I wanted to get a file's modification date in YYYYMMDDHHMMSS format. Here is how I did it:

date -d @$( stat -c %Y myfile.css ) +%Y%m%d%H%M%S

Explanation. It's the combination of these commands:

stat -c %Y myfile.css # Get the modification date as a timestamp
date -d @1503989421 +%Y%m%d%H%M%S # Convert the date (from timestamp)

Answer 5

You can use the stat command

stat -c %y "$entry"

More info

%y   time of last modification, human-readable

Answer 6

Best is

date -r filename +"%Y-%m-%d %H:%M:%S"
