Usually the date +%d gives the output 08 for the current date, 08/10/2017. But when I do the ls -lrt on a path, the date format is like Oct 8 15:03, so, how do I get the files of the current date?
I'm using the command
ls -lrt XYZ.LOG* |grep "$(date +'%b %d')" |awk '{print $9}'
but it's not giving me the file of today's date (08/10/2017) although it gives me correct output for the dates 10 - 31st of any month.
This is cheating a bit, but it works.
First create an empty reference file with a specific timestamp, namely midnight:
touch -d "$(date +%FT00:00:00)" /tmp/midnight
Then find files that are newer than this file:
find . -type f -newer /tmp/midnight
If you want ls-like output from find rather than just the pathnames:
find . -type f -newer /tmp/midnight -ls
If you want to find files matching the pattern XYZ.LOG*:
find . -type f -name 'XYZ.LOG*' -newer /tmp/midnight -ls
If you have GNU find, you may bypass the temporary file and use
find . -type f -newermt 0
to get files modified since midnight.
Related: Why *not* parse `ls`?
find, you can skip the temp file and use time strings directly with the -newerXY test e.g. find . -type f -newermt yesterday
yesterday would refer to "this time yesterday" which may cause files modified before midnight to be returned.
0 works though...
$ touch -d "$(date +%FT00:00:00)" /tmp/midnight touch: illegal option -- d usage: touch [-amc] [-t [[CC]YY]MMDDhhmm[.SS] | -r ref_file] file ...
-d flag is a POSIX standard flag. Oh well, change that line to touch -t "$(date +%Y%m%d0000)" /tmp/midnight.
You can use stat(1) to get the modified time of a file, but this is not portable.
On Linux:
$ stat -c %y some_file
2017-09-23 10:24:09.880806666 +0200
$ date -d @$(stat -c %Y some_file) +%d-%m-%Y
23-09-2017
On BSD:
$ stat -f %Sm -t %d-%m-%Y some_file
23-09-2017
how to get the files of the current date?
ls command has --time-style option to print the time in specific format:
ls -l --time-style=+'%d-%m-%Y' | awk -v d=$(date +%d-%m-%Y) '$6==d'
--time-style=STYLE
with-l, show times using style STYLE: full-iso, long-iso, iso, locale, or +FORMAT; FORMAT is interpreted like in'date';
With zsh, using glob qualifiers and age:
autoload age
print -rl ./**/XYZ.LOG*(e_'age today now'_)
or, if you prefer the long listing format:
autoload age
ls -lrtd -- **/XYZ.LOG*(e_'age today now'_)
mtime in the future but still today, so after whatever now is when you run the command until 00:00:00 tommorow. To get those too remove the argument now.
Did you try:
echo `date +'%Y-%m-%d'`*
