The reported number is the required number, not the number you are using. Thus, the 'major.minor version 52.0' error is possibly because the jar was compiled in JDK 1.8, but you are trying to run it using a JDK 1.7 environment. The error regarding the unsupported major.minor version is because during compile time you are using a higher JDK and a lower JDK during runtime. file.txt' to remove the file '-file.txt'.These are the assigned major numbers. Let say their is a file name -file.txt, to delete this file write command as: $ ls This extra dash is necessary so that rm does not misinterpret the file name as an option.

Now, deletion from A directory(as parent directory) will be done as: $ rm *Įvery directory and file inside A directory is deleted.Ĥ. Normally, rm wouldn’t delete the directories but when used with this option, it will delete.īelow is the tree of directories and files: $ ls
At each stage it deletes everything it finds. r (Recursive Deletion): With -r(or -R) option rm command performs a tree-walk and will delete all the files and sub-directories recursively of the parent directory. Note: -f option of rm command will not work for write-protect directories.ģ. Rm: remove write-protected regular empty file 'e.txt'? n The -f option overrides this minor protection and removes the file forcefully. f (Force Deletion): rm prompts for confirmation removal if a file is write protected. i (Interactive Deletion): Like in cp, the -i option makes the command ask the user for confirmation before removing each file, you have to press y for confirm deletion, any other key leaves the file un-deleted.
Note: No output is produced by rm, since it typically only generates messages in the case of an error.ġ.
Let us consider 5 files having name a.txt, b.txt and so on till e.txt.
