Hello all,
Thanks in advance.
I’m trying to find all the files with specific text in the file and have a timestamp next to the file.
Below doesn’t work, I can use the find command but it doesn’t give me the timestamp
Thanks
Dave
34. Find and Delete 100MB Files
To find all 100MB files and delete them using one single command.
Does this command find files that are greater than 100 MB?
Find files older than a prescribed number (e.g. 8) of newest files:
A little comment: Before you do something very worse with the find command, execute find without
-exec
, you see, if you do the find at the right directory or you check if find does the things expected.In this example with find / -type f -size +100M you first check, are these the files I want to delete?
Then you can add the -exec rm and so on
Thanks for these helpful examples of find command in Linux.
You should really remove this command from your example, or at least place a warning:
for sure someone unwarned might execute this and remove the directories on the root, since
rm -rf
don’t make distinction between files and directories.The correct usage would be:
since type
-f
select only the files, and removing the-r
(recursive) from rm.Still would warn about using this command, you have to be sure about running unspecific rm, even more on your root directory.
Even tho, makes no sense using rm, find already has
-delete
a tag.@Francisco,
I totally agree with you and updated as per your suggestions.
Thank you for this article it is so helpful for me
Thanks a lot please prove more article like this.
How to insert text into a already existing empty file?
You can do add content in the empty file as below
You can write anything you want.
All files have default 644 permission maximum 666 and for directory 777.
Please correct and don’t misguide people.
I’m not sure I follow. When you say default what context do you mean? The current environment umask setting affects what the ‘default‘ permissions are. Files certainly don’t have a maximum of 0666 since files can have 0777 permissions as well.
