Normally,

It is a good idea to start from the top, but the method is up to you:

Comment out all the lines except for the top line, flush iptables, reapply and test.

If it works,...

Follow ChublerXL advice. Use a less complex script, one or two lines, echoes; redirect stderr, too. Post the log files.

Have you considered inotifywait(1) (https://www.unix.com/man-page/debian/1/inotifywait/) provided by the inotify-tools package on some distributions, this can run your script whenever a file appears...

If you want the md5 operation output, use md5sum instead of ckcum

If you have lots of files and you should be ensuring that they are identical (i.e. no files missing or extra on the target) you...

rsync does that, called a hash code. If the hash code fails rsync barfs all over the place. However to answer your question:

There are several programs for this, but cksum is more than adequate....

Without a clear example of the output you hope to get and a display showing the file hierarchy you're trying to process, it is impossible to guess at what output you want. But, if you just want a...

The bash read built-in on my system doesn't have a -i init_string option, but after adjusting for that, I found that no matter what value I entered in response to the second prompt, eEpisode was...

I gave you three suggestions in post #12 in this thread that will probably work on most, if not all, of your systems. If you choose to ignore that advice, and insist on executing you bash scripts...

You may find additional inspiration in the many many threads in these fora dealing with df and mailing its results.

In the script:
df -h | {
read REST
while read FS SZ AV US PC MT REST
do useSpPer=${useSpPer}'-'$PC
echo 'use '$useSpPer
echo 'res '$PC
done
echo final $useSpPer
}
there is nothing...

From the heading you used in post #1 in this thread:
Filesystem Size Used Avail Use% Mounted on
It looks to me like the reads should be changed from:
read REST; while read FS SZ AV US PC MT...

To explain how this works, this doesn't avoid the subshell problem, as much as put the entire relevant program inside the subshell so nothing loses context.

Only Bash, Zsh and Ksh93 supports process substitution, which is what the <(...) means. Since you are invoking it with sh, judging by this # sh disk.sh , I suggest you use the command grouping
...

When you pipe something to a block, the block runs in a sub-shell.
Variables in the block are not copied back to the main shell.

A while loop is such a block.
In RudiC example the { } is the...

Try this pure shell:df -h | { read REST; while read FS SZ AV US PC MT REST; do useSpPer=${useSpPer}'-'$PC; echo 'use '$useSpPer; echo 'res '$PC; done; echo final $useSpPer; }
use -28%
res 28%...

Hi,
the effect you see is caused by the way you feed your loop. The pipe creates a subshell which has its own copies of the variables, the ones in the parent shell are not affected by actions in the...

Sure:
awk '
$2!="OK" { # if the second field is not equal to OK
t++ # increase total
$2="(" $2 # prepend opening parenthesis to the second field...

Try:
awk '$2!="OK"{t++; $2="(" $2; $NF=$NF ")"; s=s $0 "\n" } END{printf "The number of damaged tables is %s\n\n%s",t,s}' file

You can put it in a variable:
nCheck=$(awk '$2!="OK"{t++; $2="("...

grep -v "OK" is another option to exclude lines with string "OK".

In your awk command, try printing entire line instead of just first field using just print or print $0

for tbl in ${ignoreTables[@]}
