Save files in directory as txt
Code:
 wget -x -i link.txt

The above downloads and create unique entries for the 97 links in the text file. However, each new file is saved as CM080 with a FILE extention. Is there a way to convert each file in that directory to a .txt? The 97 files are in C:\Users\cmccabe\Desktop\list\geneticslab.emory.edu\tests.

Thank you Smilie.
link.txt (3.9 KB)

Afterwards, you could run a rename in a loop. Assuming that the directory only contains the files you want, you can:-
Code:
cd target_directory
for file in *
do
   mv $file $file.txt
done

If the file names gets longer and/or the number of files increases, you may hit a limit on the length of the command line when * is expanded, so bear that in mind.

All files will be renamed, so if you have a1.file a2.file & already have a1.file.txt and a2.file.txt then results might be a little unpredictable. It may well work that it will rename a1.file to a1.file.txt and then rename the same file to be a1.file.txt.txt which might be very confusing, so make sure you start with an empty directory before you download the files and rename them.



I hope that this helps.

Hi cmccabe,

Following command may also help in same too.
Code:
find -maxdepth 1 -type f -name "*" -exec bash -c 'echo mv $0 ${0}".txt"' {} \;

You can remove echo if happy with the results.

Thanks,

You know you have just renamed a html file to a txt file, don't you?
One can hardly convert a html file to a txt file, I mean in a way that the html tags disappear (yes, you can parse it with sed, but it's not recommended)

What do you think about this (yes, it looks complicated, but it might be a way better solution)...

In the download folder;
(Make sure there are only files downloaded from link.txt, just in case...)

Code:
awk '/pdf/ {
    gsub(/^.*href = "|".*/,"",$0)
    print FILENAME,$0 >> "/tmp/tcode-pdf.txt"
    print "http://geneticslab.emory.edu/tests/"$0 >> "/tmp/list2.txt"
}' *

The above awk
  • extracts the "path" to the download link for the appropriate pdf file.
  • creates a file tcode-pdf.txt with testcode-pdfname pairs (later, this is used in the renaming process)
  • generates a download list
Code:
wget -x -i /tmp/list2.txt

This time, wget will download PDFs

Code:
awk '{ A[$1]=$2; next} END { for (i in A) print "mv \x27"A[i]"\x27",i".pdf" }' /tmp/tcode-pdf.txt | sh

This awk command will generate commands (and execute them) to rename the cryptic filename of the pdf to testcode.pdf
E.g. test-pdf.php?testid=4125 to MM123.pdf

Code:
for i in *.pdf; do
 pdftotext "$i"
done

convert pdfs to txt files.

I've experimented with one test-code and the output looks very viable Smilie

I am trying out your code junior-helper and have gotten to the:
Code:
 awk '{ A[$1]=$2; next} END { for (i in A) print "mv \x27"A[i]"\x27",i".pdf" }' tcode-pdf.txt | sh

I am getting this error:
Code:
 mv: cannot stat `test-pdf.php?testid=4405': No such file or directory
mv: cannot stat `test-pdf.php?testid=4143': No such file or directory
mv: cannot stat `test-pdf.php?testid=4432': No such file or directory
mv: cannot stat `test-pdf.php?testid=4421': No such file or directory
mv: cannot stat `test-pdf.php?testid=4415': No such file or directory
mv: cannot stat `test-pdf.php?testid=4434': No such file or directory
mv: cannot stat `test-pdf.php?testid=4391': No such file or directory

all the newly created files are in a new file path:
Code:
 C:\Users\cmccabe\Desktop\list\geneticslab.emory.edu.txt\tests2\geneticslab.emory.edu\tests

but even if I do a cd to that directory I get the same error. The code seems very useful and helpful. Thank you Smilie.

OK, I think I know what might be the issue. In your posting #1 you said
Quote:
each new file is saved as CM080 with a FILE extention
So I'm suspecting that the new files (pdfs in this case) might have such extension too.
(Note: when I downloaded the files, neither the html files (e.g. CM080) nor the pdfs (e.g. test-pdf.php?testid=4405) had any extensions.)

If you provide the output of head -3 tcode-pdf.txt and
ls C:\Users\cmccabe\Desktop\list\geneticslab.emory.edu.txt\tests2\geneticslab.emory.edu\tests | head -3 I'm sure I can tweak that awk command to behave like it was intended.
