change a specific characters to capital in a specific text

for example

else {

for fileDOC in $location/*.doc
do
echo $fileDOC | tr [a-z] [A-Z] > $fileDOC
cp $fileDOC ./DOC

done
}

fi

the fileDOC return e.g
testDir/test1Dir/test2Dir//doc1.doc
testDir/test1Dir/test2Dir//doc2.doc
testDir/test1Dir/test2Dir//doc3.doc
testDir/test1Dir/test2Dir//doc5.doc

what i want is to change doc1 and doc2 and doc3 to capital (the name of the file) and return it to the variable fileDOC

SO I have a few issues:

1. Please use [code][/code] tags around your code

Quote:

echo $fileDOC | tr [a-z] [A-Z] > $fileDOC

2. a. What were you expecting here?
b. This will now clobber anything previously inside the file. Is this what you wanted?

Quote:

3. You might need to explain this one further as the fileDOC variable is not having anything returned to it??

the program is to get files (in any directory specified by the path) that end with extension .doc and change the name of these files to capital (just the name ).

So as you are on Ubuntu you could just use:

Code:

rename -n 's/$[[:alpha:]]+$$\..*$$/\U\1\2/' $location/*.doc

Untested but something like that. When you are happy just remove '-n' and the change will take affect.

mm ok just help with this if u can

Code:

capital=$( echo $fileDOC | tr '[a-z].doc' '[A-Z].doc' )

so if i have doc1.doc
i want to change it to DOC1.doc
how i can do it using the code above (using tr )

My understanding of tr is that it is a character by character translation and has no smarts about regex, hence your example will never work.

Is there a reason we cannot use another tool?

I am sorry ... you want a more complicated way to do it? Isn't that defeating the idea of a script which is to simplify things??

aha mm i can do it in a loop using the script but i want something smarter !

mm sorry i meant to say give another one but IN simple way

Well I would have to say the rename option is probably the most simple way. Other than that I think you would have to use a loop.
Something like:

Code:

for FILE in $location/*

do

    TMP_FILE=${FILE##*/}

    TMP_EXT=${TMP_FILE##*.}

    TMP_FILE=${TMP_FILE%%.*}



    mv ${FILE} $location/${TMP_FILE^^}.$TMP_EXT

done

If there are spaces in the names you may want to put quotes around the variables.

thanks grail for the solution ...i found another solution using basename command

e.g: filename.doc

[cod] basename filename.doc .doc | tr [a-z] [A-Z] [\code]
will return FILENAME then i can combine it to .doc to get FILENAME.doc ;)

ofcourse i may use a loop to get all the file in a directory that end with .doc and change it

Nice ... I had not used the suffix option previously ... nice.
