Finding a solution for this problem was fun i must admit.
Here is one solution full bash.
This script will do as many max concurrent process as you want, just set MAXJOBS to it.
Typical usage is cat iplist.lst | thescript.sh
Code:
#!/bin/bash
# Max concurrent job process
MAXJOBS=60
trap "kill 0" EXIT
IPLIST=($(cat))
index=0
index_count=${#IPLIST[@]}
function doping {
local ipad=$1
if [ -n "$ipad" ] ; then
ping -c4 -q $ipad &>/dev/null
[ $? -eq 0 ] && echo "Host : $ipad is up" || echo "Host : $ipad is down"
fi
}
while [[ $index -le $index_count ]]
do
# The current ip
IPADDR=${IPLIST[$index]}
NBJOBS=$(jobs -p | wc -l)
if [ "$NBJOBS" -lt "$MAXJOBS" ] ; then
doping $IPADDR &
((index++))
continue
fi
done
wait
Tested it with 400+ Hosts and MAXJOBS=200 it was faaast
Just a super quick question:
how do you put a link in your php code.
I want to make a link to something in /tmp directory.
i.e. how do you put a href into php, I think it's done a bit differently.
thanks

Hi,
At best I'm a junior admin with a big problem.
My developers have got my root password and mgmt insists they need it.
I can't even change it when people knowing it leave.
I'm certain they've hardcoded it into routines. I've searched my servers and grepped everything & can't find it.

git-merge-index
GIT-MERGE-INDEX(1) Git Manual GIT-MERGE-INDEX(1)NAME
git-merge-index - Run a merge for files needing merging
SYNOPSIS
git merge-index [-o] [-q] <merge-program> (-a | [--] <file>*)
DESCRIPTION
This looks up the <file>(s) in the index and, if there are any merge entries, passes the SHA-1 hash for those files as arguments 1, 2, 3
(empty argument if no file), and <file> as argument 4. File modes for the three files are passed as arguments 5, 6 and 7.
OPTIONS --
Do not interpret any more arguments as options.
-a
Run merge against all files in the index that need merging.
-o
Instead of stopping at the first failed merge, do all of them in one shot - continue with merging even when previous merges returned
errors, and only return the error code after all the merges.
-q
Do not complain about a failed merge program (a merge program failure usually indicates conflicts during the merge). This is for
porcelains which might want to emit custom messages.
If git merge-index is called with multiple <file>s (or -a) then it processes them in turn only stopping if merge returns a non-zero exit
code.
Typically this is run with a script calling Git's imitation of the merge command from the RCS package.
A sample script called git merge-one-file is included in the distribution.
ALERT ALERT ALERT! The Git "merge object order" is different from the RCS merge program merge object order. In the above ordering, the
original is first. But the argument order to the 3-way merge program merge is to have the original in the middle. Don't ask me why.
Examples:
torvalds@ppc970:~/merge-test> git merge-index cat MM
This is MM from the original tree. # original
This is modified MM in the branch A. # merge1
This is modified MM in the branch B. # merge2
This is modified MM in the branch B. # current contents
or
torvalds@ppc970:~/merge-test> git merge-index cat AA MM
cat: : No such file or directory
This is added AA in the branch A.
This is added AA in the branch B.
This is added AA in the branch B.
fatal: merge program failed
where the latter example shows how git merge-index will stop trying to merge once anything has returned an error (i.e., cat returned an
error for the AA file, because it didn't exist in the original, and thus git merge-index didn't even try to merge the MM thing).
