Description
Read the Linux manual for commands find and tar and write a Bash
script, call it organize, to collect and copy files, from a target
directory hierarchy, with specific extensions, into a number of tar files,
to be saved in a destination directory.
Synopsis:
organize [-t tarDir] [-o orgDir] organize should use command find to visit each file in the
hierarchy, defined by the root directory tarDir, and if their
extensions are in extensionList, the files are copied to the directory
orgDir, where each group of files with the same extension are tared to
a single file called, extensionName.tar (e.g. doc.tar) then deleted
(only tar files are to remain).
Additional Rules:
When orgDir is missing, then directory orgDir should be created in current
directory (PWD) and used for tar files.
When tarDir is missing, then current directory (PWD) should be used as
target directory.
The script should check if orgDir exists (when provided) and if it has
write permission. Otherwise, your script should exit with an error
message. • Since command find might find multiple files with the
exact same name and extension in different subdirectories of the hierarchy, your script should first check
if the same name already exists in orgDir,
2
in which case you should add 1 or 2, etc. to the
destination file name resulting from the copy.
Below are some sample runs:
Example 1:
$ organize -o ∼/save txt doc
//Note: -t tarDir is not listed, and therefore the PWD should be
assumeD as tarDir
Searches all files whose extensions are either txt or doc
in the whole directory hierarchy (root is current directory, that is,
.), creates ∼/save if it does not exist already, then copies all these
files to ∼/save (make sure same-name files are copied properly).
Then, all txt filesare tared as txt.tar and all doc files are tared as
doc.tar. Example 2:
$ organize pdf doc txt
//Both -t tatDir and -o orgDir are not listed
Searches all files whose extensions are either pdf, doc or txt in the
directory hierarchy (root is .), creates orgDir then copies all these
files to it and tar them accordingly.
Submission:
Submit a single file organize.sh
