I'm writing a script to delete large number of files in linux. The script will run every two minutes in crontab. I tried using the
find /mnt/md0/capture/DCN/ -maxdepth 1 -type f -name "*.pcap" -print0 | xargs -0 ls -lt | tail -$del | awk '{print $8}'
and saving this to a variable and tried to delete using rm command, but dint run. I have found out that find . -type f -delete can be used to delete the files, but I don't know how to add this part to my command. How would I do this?
Just replace -print0 with -delete:
find /mnt/md0/capture/DCN/ -maxdepth 1 -type f -name "*.pcap" -delete

I want a shell script to compress all the log files in "my_dir" directory after the configurable number of hours or days.
I have tried with the following script but it didn't work :
find /path/to/directory -mtime +2 -exec ls "{}" \
find /path/to/directory -mtime +2 -exec ls "{}" \;
The script is getting executed but no action is done.
Maybe you just want configure the logrotate on server, see this link: https://www.thegeekstuff.com/2010/07/logrotate-examples
And if you want execute at any time, you can call for an execution with this command (but it's unnecessary if the config file had correctly configurated):
#: logrotate /path/to/my/logRotateFile.conf
You can try this command for hours configuration:
find /path/to/directory/*.log -type f ! -name "*.tar.gz" -mmin +$[$COMPRESS_HOURS * 60] -exec mv '{}'
COMPRESS_HOURS are configurable
And for days
find /path/to/directory/*.log -type f ! -name "*.tar.gz" -mtime +$days -exec mv '{}'
days are configurable

I would like to be able to create a copy of a directory tree and soft link the files on it.
For example, from
/home/user/origin/a/sub/file.txt
I would like to get
/home/user/destination/a/sub/file.txt
being this one a link to the original file.txt.
I tested with
find /home/user/origin/ -type d -printf "mkdir -vp '/home/user/destination%p'\n" -o -type f -printf "ln -vs '%p' '/home/user/destination%p'\n" | sh
but it has two problems:
I'd like to copy from origin to destination, and it copies from origin to /home/user/destination/home/user/origin. It is not a biggie, as I can move that afterwards
If the file name is something like
In Fifty Years We'll All Be Chicks.txt
It stops working because the '.
Assuming I understand what you're trying to do, it seems easier to just use -exec
find /home/user/origin/ \
-type d -exec sh -c 'mkdir -v "/home/user/destination/${0#/home/user/origin/}"' {} \; \
-o \
-type f -exec sh -c 'ln -vs "$0" "/home/user/destination/${0#/home/user/origin/}"' {} \;
Note -or having lower precedence than the implied -and's is important here.

For counting the number of files in directory i know two methods
first one ls -l file* |wc -l
second one find file* -type f -maxdepth 1 | wc -l
which one is more relibale and correct one?
Prefer the find option, but use -name 'file*' (in single quotes), as in
find . -maxdepth 1 -name 'file*' -type f | wc -l
This will avoid globbing, as both examples above I believe may run into a max args limitation.
`/home/charles/data/Study$ find . -maxdepth 1 -name CL* -type f | wc -l
bash: /usr/bin/find: Argument list too long
`/home/charles/data/Study$ find . -maxdepth 1 -name `CL*` -type f | wc -l
318480
There is no such solution for ls, so find is slightly more dependable. This is all dictated by ARG_MAX, as in:
`/home/charles/data/Study$ getconf ARG_MAX
2097152 # in bytes

I know I should assign a group and then set an umask so that groups writable permissions persist but for whatever reason I can't do this. I need to chmod recursively a directory except one sub folder (web10), would the following work?
cd /var/www/clients/
find . -type f -not -path "*web10*" -exec chmod 777 '{}' \;
If you want to exclude files or directories, you use -prune
find /var/www/clients/ -name web10 -type d -prune -o -type f -print0 | xargs -0 chmod 0640
You should also use xargs where possible. With -exec you call the command once for every file found, whereas xargs collects as many files as possible and calls the command once for N files, resulting in a more efficient execution and better performance.

The command below moves every hidden/normal file ending with *string without . or _ before it.
mv {.,}*[!._]string /destination
How can I also exclude moving all directories in the above command?
Try
find /WHERE/TO/FIND -name '*STRING' \( ! -name '*_STRING' -o ! -name '*.STRING' \) -type f -exec mv \{\} /WHERE/TO/MOVE \;
Note, if you want to move every file from only the /WHERE/TO/FIND directory, you should add -maxdepth 1 (after e.g. the -type f part).
How about:
for file in {.,}*[!._]string; do test -f "$file" && mv "$file" /destination; done
In what shell does the [!._] glob actually work when used with {.,}? You would probably be better off avoiding the {} notation and do:
for file in .*[!._]string *[!._]string; do ... ; done
