Following example will find files in the current directory and sub-directories, whose content got updated within last 1 hour 60 minutes. To find the files based up on the file access time, the option -amin, and -atime is used.
Following is the definition of amin and atime from find man page. Following example will find files in the current directory and sub-directories, which got accessed within last 1 hour 60 minutes.

But having space in the file name is not so good for Linux kind of systems. You can use the find and rename command combination as shown below to rename the files, by substituting the space with underscore. As shown in the examples of the find command in its manual page, the following is the syntax which can be used to execute two commands in single traversal. If you need to return, bookmark this page at del. Hi, I sometimes use this command in a bash shell to substitute space with underscore in a whole tree files and directories.
Very Nice…helps alot i believe.. Hope to have your help on this as well.. This process of detecting the file s modified in the last 10 or 15 minutes shall go on. There are totally 41 files that i have to look out from and once such files are redirected , then i have to Open and Read only the Latet ENtries from such files.
Hope this would make the requirement further a bit more clear. I had search for such clear exemples for a loooong time before today. Thank you very much Vimash for taking time to share your knowledge in such a nice way —especially with a beautiful baby like yours ;-D.

Hi Ramesh, Thanks for all your brilliant work!! Now , Unix looks easy to me. The choice of your presentation is awesome. Hi great work. Hi , I think there is some missing in the example How can i find the files updated in last two days, But there is a condition i want to exclude a folder eg : test while searching this.
What command it should be. Check the folders and identify the last updated time of all files. Delete all files that are older than 30 days.
On the remaining files, check the size. If size is more than 2 MB, ask an option by the user to pass an argument to the script based on time, or based on size trimming the files to 2MB. How do I find the number of files that were created in a week say from Monday 14th to Monday 21st and How to I grep for a pattern in these files only.

35 Practical Examples of Linux Find Command
The Linux find command is very powerful. It can search the entire filesystem to find files and directories according to the search criteria you specify.

Excellent examples, but did you know you can omit all of those "-print" parameters? Print is the default command for find. Piping a list of file nnames through "xargs grep" will fail if "find" locates files that contain spaces in their names, since by default "xargs" splits the incoming list on spaces. In that case, use "-print0" on the "find" command to separate file names with nulls, and "-0" on "xargs" to tell it the file names are null separated. When using xargs and you know some files will contain spaces, use -print0 and -0, like so: find.
