Using GNU date:
$ date --date="Dec 11" +"%Y-%m-%d"
2014-12-11

Try this:
#!/bin/bash
typeset -i interval=5
run=true
trunk=vonage
reboot=0
while [[ "$run" == "true" ]]; do
checktrunk=$(asterisk -rx "sip show peer $trunk" | grep -c "Status.*OK")

Nice & clean @Yoda , just one point i .. i would use next to avoid the second matching this way:
awk '
/>/ {
$0 = ( NR == 1 ? $0 : RS $0 RS )
print
...

Add tou your ssh:
-o ConnectTimeout=n
Where n is compute as seconds.

Hi @wisecracker, i just wanted tho show a practical usage of look-ahead/behid assertion, for me the important thing here is not the print statement and of course i can't guarantee python in all *nix...

I would choose another python approach by using datetime calculation facilities:
#cat filter.py
#!/usr/bin/python

import sys
import datetime

first_offline = {}
with open(sys.argv[1],'r')...

Try this logic:
#!/usr/bin/python

import re
import ping, socket
import subprocess
from subprocess import Popen, PIPE

pattern = re.compile(r'inet.\S+(\S+\d+\.\d+\.\d+\.)')

p1 =...

Quick dirty awk:
awk 'NR==1{L=$NF<$(NF-1)?$NF:$(NF-1)}$(NF-1)<= L{L=$(NF-1);t=$0};$NF<=L{L=$NF;t=$0}END{print t}' infile

You should pick one tool and keep stick to it.
A starting point to give python a try:
#!/usr/bin/env python
import re
import sys

pattern = re.compile(r'''
...

Interesting regex (python shell again):
>>> text = '''
... @LIB ADVAPI32.dll @CAL RtlInitAnsiString @PA1 0x0012f740 @PA2 "CriticalSectionTimeout" @RET0
... @LIB ADVAPI32.dll @CAL...

python shell:
>>> import re
>>> text = '''
... Server Stopped
... ABC
... DEF
... GHI
... JKL
... Server Started
... MNO
... PQR
... STU
... Server Stopped
... VWX
... YZ
... ABC
......

From python shell:
>>> import re
>>> text = '''
... @LIB ADVAPI32.dll @CAL RtlInitAnsiString @PA1 0x0012f740 @PA2 "CriticalSectionTimeout" @RET0
... @LIB ADVAPI32.dll @CAL memmove @PA1...

Try:
sort -un inputfile

Not sure if i understood correctly, but this may helps:
# awk '{a[$NF]=sprintf("%s%s ",a[$NF],$1)}END{for (i in a){print i,a[i]}}' infile
1.1.1.1 app1 app3
1.1.1.2 app2
1.1.1.3 app4

Give this a try:
awk '/<\/RECORD/{
print raw""$0 > name".xml"
name=""
raw=""
next}
...

Another way:
ls *_2010*| sed -e "p;s/_2010/_2014/"|xargs -n2 mv

In a oneliner:
perl -ne 's/(\s*|\n)//g;print $_' inputfile
Inside a multiline script:
perl -e 's/(\s*|\n)//g && print $_ foreach (<>);' < inputfile

ok , use:
file_avail=`ssh username@host 'if [[ -f "directory/structure/Daily Report.xls" ]]; then echo 1; else echo 0; fi'`
Personally , i prefer:
ssh username@host 'if [[ -f "Daily Report.xls"...

Python re module maybe handy for that task:
echo "abcd fkaj&dsdsd;"|python -c 'import re;import sys;print re.escape(sys.stdin.read().strip()),'

As simply as:
s= int(line[1])-1
In your original script.

Try with this less verbose example:
#!/usr/bin/env python
import sys
from decimal import Decimal
with open(sys.argv[1],'rb') as f:
for number in f:print str(Decimal(number))
About Python...

Try:
scp -B -p ${Auser}@${aSrcHOST}:${aSrcDIR}/*.[Oo][Kk] $aTgtDIR

If perl is ok:
perl -lane 'if (/Name:\s+(\S+)/){$group=$1};if(/^\s*(\d+)\s+(\S+)\s+(\S+)/i && $group){print $2.",".$3.",".$1.",".$group}' infile

Or:
if [ "$ServerName" = "usei01" -o "$ServerName" = "usei02" -o "$ServerName" = "usei03" ]

The perl equivalent:
perl -lane 'print $1 if /(<a href[^>]*>)/' infile
