Shell Programming and Scripting

There can be multiple files, and the structure of the filename can be different but it has hyr in the filename. So if filename contains hyr word and it has .md and .db extension; it will move to TUM/HYR folder; if extension is .txt it should convert using dd command to edcdic and move it to TUM/HYR
if filename contains par word and it has .md and .db extension; it will move to TUM/par folder; if extension is .txt it should convert using dd command to edcdic and move it to TUM/PAR
if filename contains mar word and it has .md and .db extension; it will move to TUM/mar folder; if extension is .txt it should convert using dd command to edcdic and move it to TUM/MAR..
Can anyone help me with the entire script so that I can test it...

One important thing I missed is; all these files and folders are in Hadoop HDFS.

Main folder is MUM
SUBFOLDERS ARE HYR PAR MAR... there can be multiple such subfolders
But the subfolders and the files in it has a match with filename,like if HYR is a subfolder it will hv a file name which has hyr_20162001.md and db in it, so the script can pick word hyr from filename.

So script will read main MUM folder and the all the subfolders one by one and copy file into out directory which is :-
TUM/HYR for hyr files with .md .d
TUM/PAR for par files with .md .db
TUM/MAR for mar files with .md .db
TUM/SAR for sar files with .md .db
remember there can be other subfolders as well but it has a standard like lets assume I hv other subfolders called ABC so the file in it will be abc_20162019.db and md and it will be copied into TUM/MUM folder..

Note all these files and folders are in Hadoop so it will be Hadoop commands. Not sure if above unix command like find and all will work or not

Just repeating the info given in post#1 doesn't really help. Info on the contents of directories might be extremely beneficial, like will there be "hyr" files in the "PAR" subdir, and e.g. a (partial) directory listing.
Adding lately that *nix commands probably don't work is, hmmm, debatable.

Apologies RudiC, to answer to ur question.
hyr file name will be there in HYR subfolder, par filename will be in PAR subfolder and so on... I'm not sure about unix command will work or not... Actually these main folder MUM and it's subfolders N files are in Hadoop and I want to copy these to destination folders as mentioned in my earlier post...
Hope that clarifies...

Hello all,
A quick solution will let me move ahead...
Do share a script for further analysis

The UNIX & Linux Forums is here to help you learn how to write your own code; the volunteers here are not your unpaid programming staff.

RudiC has given you code that you should be able to mold into something that will meet your requirements. RudiC also asked questions that you have not answered that would provide information that would greatly simplify code that I would write if I were trying to solve your problem. You were asked to show us the output of ls (which would clearly demonstrate the format of your filenames). You have shown us one relative pathname (TUM/ABC/abc_20162019.db), if all of the filenames you want to process follow this filename format (i.e., 3 lowercase letters; <underscore>; 6 decimal digits; and one of the three filename extensions: .db, .md, and .txt), then code could be significantly simplified. If we knew that there are no files in those directories that do not conform to the above filename format, code could be simpler still.

If you would like our help to complete your project, please answer the questions that have been asked, show us the code you have tried, show us what is working, and explain clearly what still needs to be done.

Apology Don Cragun and RudiC. But I did replied to the questions raised by RudiC. File name will contain project_abc_20162012.db & md and .txt as well.
So again if I would reiterate, the main Folder is MUM and the subfolder is ABC anf this subfolder u will hv 3 or more files and these files will be copied to output folder which is TUM/ABC by searching abc word from the filename and .db & .md in it.
This folder can contain other files as well but they will stay there in the same folder only the file which matches the above criteria will move to output folders.
As of now I'm copying these files manually...
I search files in MUM/ABC folder which contains abc word in filename and which has .md and .db extension and copy those to TUM/ABC folders.
Same process I do it for other subfolders par sar mar.
Key point- the folder name has the relavant filenaming convention files in it.like PAR subfolder will hv project_par_20162010.db .md and .txt files in it which has to be moved to TUM/ PAR destination folder.
Iam hoping this clarifies..

Most important thing- all these files and folders are in Hadoop HDFS.

Sincere apology for the trouble...

Try to replace for i in MUM/*/* in post#7 with

Code:

for i in MUM/*/*.{db,md,txt}

and post where this approach doesn't meet your needs. This is all I can (and will) do until you stop repeating the well known info and give the necessary ones.
