[CentOS] Shell Script: Simple array usage = bad substitution?
Hey Guys n Gals;
I have some arrays that I can't seem to expand correctly (if that's
the correct word?), imagine the following example:
#!/bin/bash
myArray=(First Second Third)
First=(Monday Tuesdays Wednesday)
Second=(One Two Three)
Third=(A B C)
for ((i=0;i${#myarr...@]};i++))
do
for ((k=0;k${#${myarray[$i...@]};k++)) # Things go bad here!
do
echo ${${myArray[$i]}[$k]} # I understand this line
is won't work but it doesn't matter right now
done
done
So ultimatly we shall loop round each value in the myArray array and
print out the values in each array which has the same name as the
value in the myArray, array.
Where I have marked with a comment, the script stops with the error-
: bad substitution
I have looked on-line but I don't quite understand how I can correct
this? I have seen other people have this error for other problems but
not one like mine so I don't fully understand it? Can anyone explain
to me exactly what is going wrong and how I might correct it?
James ;)

How about this? Avoids the c=like for loop increments and just uses
the array elements for the next loop ...

[CentOS] Shell Script Pointers?
Hey Listee's
I am trying to write a shell script to sort and compare my blacklist
for squidGuard with the nightly updates that come down in a tar ball.
It should be rather simple but I'm not to grate at this. The script is
to run nightly, it will download the latest blacklist tarball, un tar
it and then add any new entries to the existing black list. The
blacklists work by having a folder for each filtered category so the
folder db contains the subfolders adult, gambling, drugs etc
and each sub folder has two files, domains and urls (pretty self
explanitory). This is how far I have gotten (I haven't tested this
script yet as I haven't had a chance I have only gotten as far as
writting it, this is what I have so far:
#!/bin/bash
#This will be running from home directory
wget http://www.blacklistsite.com/blacklist.tar
tar -cxf blacklist.tar
cd BL
find ./ -type d -maxdepth 1 | while read FOLDER; do
SQUIDDB=usr/local/squidGuard/db/$FOLDER
sort_db($SQUIDDB)
comm -3 $SQUIDDB/domains $FOLDER/domains $SQUIDDB/domains.missing
comm -3 $SQUIDDB/urls $FOLDER/urls $SQUIDDB/urls.missing
cat $SQUIDDB/domains.missing $SQUIDDB/domains
cat $SQUIDDB/urls.missing $SQUIDDB/urls
rm $SQUIDDB/domains.missing
rm $SQUIDDB/urls.missing
sort_db($SQUIDDB)
done
sort_db(){
sort -f $1/domains $1/domains.sorted
sort -f $1/urls $1/urls.sorted
rm $1/domains
rm $1/urls
mv $1/doamins.sorted $1/domains
mv $1/urls.sorted $1/urls
}
Is it obvious I'm new to this? Hehe, I would also love to hear how
people would do this in a more efficient manner because obvisouly this
is pretty sloppy and as I said I haven't tested it yet so it might not
even run?!
Thanks, James ;)

[CentOS] Shell Script - Compare packages. rpm.

Since a file is the output of the command rpm-qa pkg.out
And the second file is a list of several packages rpm's, multiple versions
and architectures.
Just for the fun (and did not really test it):
cat pkg.out
|
awk ' { p=$1; n=match(p, -[[:digit:]]+); print substr(p,1,n); } '|
while read PKG; dogrep $PKG[0-9] update.out; done
I will leave you as an exercise to sort the results by versions and head (or
tail) to keep the highest one... ^_^
But, if your update.out file contained only the latest package (and not all
different versions), that should work.

In all likelihood the system follows the default approach of setting the primary group to be the user's personal ground. If that is the case then you're correct in providing a simple solution as requested.

The egrep is using a leading anchor (^) to make sure the grep matches the
beginning of the line. If not, and the group pattern matched as one of
the users it would print those lines too .. which is probably undesirable.

If you have a list of hosts in a file, you could do: for host in `cat [filename]` do ping -c10 $host done or: while read host do ping -c10 $host done [filename] If you only want to ping each host once, you can substitute '-c10' with '-c1' (again, see the man page).

In zsh, it would be something like:
for i in {..}; do
echo $i
