Can anyone help me finding solution to my requirement.
the requirement is I have to write a shell script which will scan a directory and read each file coming to it and will search for a string starts with (like "AB00732614") It will search for all files which contains AB* then it will move the file to another directory.
Assuming that the string AB-etc. is part of the contents of the files to be moved:
find /path/to/dir -type f -exec grep -qE 'AB[0-9]{8}' {} \; -exec mv -i {} /path/to/destination/ \;
This uses find to find all regular files under /path/to/dir. For each file, grep will look whether it contains anything matching the extended regular expression AB[0-9]{8} (the string AB followed by exactly eight digits). If it does, the file is moved to the directory /path/to/destination/.
If another file with the same name as the file being moved is already in the destination directory, you will have to confirm that you would like to overwrite that file.
You can use:
find . -type f -iname 'AB*' -exec mv -t ./another_directory/ {} \+
It is very well explained here: https://stackoverflow.com/a/5607677
ab or Ab or aB (and will only move regular files, not the other types of files like directory, symlink, device, fifo...)
mv dir1/AB* dir2?
