Hi,
i tried to search a string, recursively, in subdirectories with:
find . -type f -print | xargs grep -s hello
i found all files that contain the string "hello"
but i would perform a search also in symbolic link, so i tried with find -L . -print | xargs grep -s hello
but no result was returned ?
Could you help me, please ?
The grep utility searches for text in the file a symbolic link points to; it does not search for text in the symbolic link itself. Some systems provide a readlink utility that will display the contents of a symbolic link that could be used as:
where grepsym is the following shell script:
If your system doesn't come with a readlink utility, it is easy to write a C program that prints the results returned by readlink(argv[1]).
Depending on your application, you might also be able to use the output of ls -l symlink (which will display the contents of symlink at the end of the output.
PS: It is not necessarily true that:
will not print anything. That command will print the names of every symbolic link in and under the current directory that points to a file that does not exist.
