Listing files older than 30 days
Hi,

Could someone help me that what the problem is in this code?

Code:
#!/bin/sh 

FOLDER=/abc/datasource/checkstatus
 
TIMESTAMP=$(date +%s) 

for filename in $(find $FOLDER -maxdepth 1 -type f -name "CHECK_STATUS*"); do

f1=$($filename -Eo "[0-9]{4}[0-9-]+")

f2=$(date -d "$f1" +%s)

if $TIMESTAMP-$f2 -gt 2592000; then 

echo $(basename "$filename")

fi

done

exit 0;


Thank you.

Wow Smilie

Before I try to work with it, have you considered using the -mtime flag on find? It might save you a lot of effort.



Kind regards,
Robin

What do you think yourself what the errors might be? What error messages did your shell issue when you tried to run the code? Did you try? Did you consider the -x option running it?

Yes, I've tested with -mtime and it works fine. but sometime we are moving files to other folder and then the -mtime doesn't work to list them, then the best way is to extract the date from filename.

Thank you.
It would be helpful if you post a few CHECK_STATUS* entries to examine.
It would be helpful if you post what the errors are. You can post the output of the code running with the flag -x.
It would be helpful if you post the os and shell type you are using.
Code:
for filename in $(find $FOLDER -maxdepth 1 -type f -name "CHECK_STATUS*");


Code:
f1=${$filename -Eo "[0-9]{4}[0-9-]+"}

Take a look how Parameter substitution works.

Code:
if TIMESTAMP-$f2 > 2592000; then

Take a look at arithmetic expressions

I changed some part of the code but the for loop shows all files and not those that are older than 30 days and also the result for $(TIMESTAMP-$f2) is the same for all file name that is listed, here is an example of output:
Code:
./list.sh: line 11: /abc/datasource/checkstatus/CHECK_STATUS_PARTY_CODE_2017-08-31_114506.txt: Permission denied
./list.sh: line 15: 1508845131-1508796000: command not found
./list.sh: line 15: command not found
./list.sh: line 11: /abc/datasource/checkstatus/CHECK_STATUS_PARTY_CHANGE_2017-10-17_114526.txt: Permission denied
./list.sh: line 15: 1508845243-1508796000: command not found

I've changed the code before reading your comments :-)
but I ran the code with ./list.sh -x and results were the same.

Would you prefer to re-write this as Perl, or can you alter the f1= statement to meet your needs?

If you say something like "It doesn't work" without the current code, input, output & error messages it can be extremely hard to follow through. Can you help us out here?

Please paste them in CODE tags. The tutorial is below:-
