Redirection works identical for input as well as for output. Try

Would this (https://www.unix.com/303046306-post5.html) point you in the right direction to adapt your script?

Adapting your own attempt, try
awk 'NR==FNR {a[$2 $4] = $6; next} a[$2 $4] != $6' FS="," file1 file2

Depending on how you copied the .iso to the pen drive, the msdos formatting is gone, and iso9660 would be the FS type of choice. It has many mount options that might help in getting your task done.

What about cd0 / cd1? Looks like it thinks your iso is on a CD?

It doesn't. It would remove any line with an emtpy $1, of which there is none. You can leave it out entirely. The $4 < 7000 removes the header line. $4 > 7000 would not; we'd need a different...

Better than what? Any attempts / ideas / thoughts from your side?

Try this:
awk '$1 == "Name"; $4 < 7000 {print | "sort -k4"}' file

Or, awk:
awk -F"[,;]+" 'NR == 1 {print; next} {for (i=2; i<=NF; i++) print $1, " " $i}' OFS=, file
Name , Company_Worked (Header)
Asley, IBM
Asley, Amazon
Asley, BOA
Asley, Google

Try this for leading header and sorted data:
awk 'NR == 1; $4 < 7000 {print | "sort -k4"}' file
Name tDesignation tDepartment tSalary

That's because if your first printout trigger /-/ is hit, only that array element is set yet. On top, all further date/time stamps do not match the data printed with them; the data are shifted one...

I can't quite follow this request, nor do I understand its relation to the title "Ssh newbie", but if you have a file name stub in a variable that, in real filenames, is followed by two digits, which...

32 bit overflow? Calculate

No surprise. Shells don't expand variables enclosed in single quotes. Use awk's standard mechanism to convey variables: the -v option. Like
awk -F "," -v"USER=$usr" ' $1 == USER {print $2}'...

Unfortunately, awk doesn't have the --recursive option that grep provides. But we can resort to bash's "brace expansion" for sweeping across the directory tree and "extended globbing" ("extended...

Run the ps $id outside the for hugepagesize ... loop. Same for the echo $total_num_hugepages. echo each result within. Adorn your echoes with the desired text.

As ususal: what OS and shell versions?


In (recent) bash, set the pipefail option:
$ set -o pipefail
$ ls -l fxxxx | tee -a file2 | tee file1
ls: cannot access 'fxxxx': No such file or...

Try
sort -t. -k1,1 -k2n file

Looks like /usr/xpg4/bin/grep works as expected; why not try /usr/xpg4/bin/awk, then?


For your other problem:
Remove the .log entry from filesdone upfront, with e.g. sed. Or do so with a...

I'm afraid that sed script doesn't lead you anywhere. Try
$ awk '/^Date/ {TMP = $2; next} /^Time/ {if (!HDDone++) print; next} !/^ *$/ {print TMP "_" $0}' file

Not sure why you should need cron for your task, but this should run under it as well. Make sure it is run by bash! Replace your if construct with
if [ $(ls ${error_dir} | grep -c "\.err$") -eq 0 ]...

Why check for duplicate files if you can avoid producing them in the first place? Try
$ touch filesdone
$ awk -vLCNT=10 -vPAT="CORRUPTION DETECTED" '

In the loop, will the .err files be removed on later success? How to tell new errors from old ones during the loop? Will there be leftovers from the last run?
What wait period between loops do you...

Try also
