I've never actually seen this option myself, but it seems quite useful.

Just out of interest, when using it to create a script, how do you convert it to non-encrypted form for execution?

Thanks

Hello all

I'm experimenting with the use of the -prune action and I've encountered some confusing behaviour when using the -o option. Can't find anything specific in the man page.

If I have a...

sort -t, -n -k2 filename >./sorted_filename

Hi Helen

I think the issue with variable-expansion and noglob is only a problem when doing your 'eval'. Setting noglob to on shouldn't affect it otherwise. I think I'm roughly using your...

Apologies, I may have been a bit hasty in suggesting that in that way. noglob prevents wildcard characters from being expanded.

I don't know exactly how you'll be extracting your variables from...

You could set -o noglob before the eval and then set +o noglob after.

Just a guess, but I think the . command is instructing the current shell to interpret the script - which it can't because it has perl commands/functions in it.

I'd use perl for something that involved.Something like:-

#!/usr/bin/perl

# Use Perls localtime function if you want, but this is plainer
$date=`date '+%d_%m'`;
chomp($date);

csplit should do the job, try 'man csplit'

It's the same issue - the shell you're using can't deal with non-integers.

Use the same technique as jim has shown - pipe the expression through to the bc function.

For files you can use:-

find /filesystem -size 0c -print

Are you redirecting your output to another file? That command won't change the file itself.

Ok, run the script for each possible value of v_id and echo out the values of $v_flag.

Or alternatively, add the loop back, but edit it each time to run only one of the potential values of v_id...

The posts above tell you everything you need to know (plus you've answered your own question with the example of the script that works when called by the cron).

Your .profile contains environment...

Try:-

mins=$(echo $time|sed -n 's/.*[^0-9]\([0-9][0-9]*\).*/\1/p')

hrs=$(echo $time|sed -n 's/\([0-9][0-9]*\)[^0-9]*.*/\1/p')

I think that should give you the hours and minutes whatever...

Well I'm still not convinced it's because the query's returning nothing. It sounds more like it's returning something the query can't handle, but why not try putting quotes around the variable in the...

I can's see any reason why not - are you sure that's the problem?

I'd echo out the value of $v_flag for each iteration and see what it actually contains. It may be that it has some unexpected...

If mdbase is the end of the field or word separated from whatever follows by whitespace you can use:-

grep "/backup/surjya/mdbase\>" xmldir.conf_backup | wc -w

use :-

if [[ $choice -lt 1 || $choice -gt 7 ]]
then
.....
fi

Try :-

grep '^[A-Z][A-Z|a-z]*[tcz][A-Z|a-z]* .*[0-9]*[02468][0-9]*$' /home/public/data.txt

as your grep

Your test condition is always going to be true.

If you enter 'y' for the $true variable then "$true != 'Y'" will be true, if you enter 'Y' for the $true variable then "$true != 'y'" will be true....

Well you're doing a head and a tail, so you're deliberately removing some (arbitrary) results from the grep.

I may have misunderstood your problem and I've gone a bit 'quote-blind' looking at your output, but it seems to me the single quotes are there because you're running the script in debug mode and the...

Well awk can handle non-integer arithmetic, but not standard bash or tcsh.

It was indeed - should have taken my own advice and cut-and-pasted from the terminal!

Apologies for that. Cheers vgersh99.
