If “pip” installed 64-bit libraries, while python is a 32-bit binary, “pkg” might stop working with the following error messages:
ImportError: ld.so.1: bootadm: fatal: /usr/lib/python2.7/site-packages/lxml/etree.so: wrong ELF class: ELFCLASS64
ImportError: ld.so.1: python2.7: fatal: /usr/lib/python2.7/site-packages/_cffi_backend.so: wrong ELF class: ELFCLASS64
$ file `which python` /usr/bin/python: ELF 32-bit LSB executable 80386 Version 1 [SSE], dynamically linked, not stripped
The workaround is to remove the corresponding python packages (in this case cffi and lxml), download and recompile them manually with “-m32”:
$ export CFLAGS="-m32"
This one-liner takes Cisco ASA config, checks for “tunnel-group … remote-access” and generates the following two lines:
tunnel-group GROUPNAME webvpn-attributes group-url https://CISCO_ASA_FW_FQDN/GROUPNAME enable
for i in `fgrep tunnel-group CISCO_ASA.conf | fgrep remote-access | awk '{print $2}'` do echo "tunnel-group $i webvpn-attributes" echo " group-url https://CISCO_ASA_FW_FQDN/$i enable" done
Let’s search for “red apple”:
For Solaris (use gsed instead of sed):
curl -A "Mozilla/5.0 (X11; SunOS i86pc; rv:52.0) Gecko/20100101 Firefox/52.0" \ 'https://www.google.nl/search?q=red+apple&tbm=isch' 2>/dev/null | \ tail -1 | gsed -e 's/,"ow":/*/g' -e 's/,"ou":/*Image:/g' | \ tr '*' '\n' | grep "^Image" | sed -e 's/^Image:"//' -e 's/"$//'
For Linux:
curl -A "Mozilla/5.0 (X11; SunOS i86pc; rv:52.0) Gecko/20100101 Firefox/52.0" \ 'https://www.google.nl/search?q=red+apple&tbm=isch' 2>/dev/null | \ tail -1 | sed -e 's/,"ow":/*/g' -e 's/,"ou":/*Image:/g' | \ tr '*' '\n' | grep "^Image" | sed -e 's/^Image:"//' -e 's/"$//'

From my explanations of the set theory to my daughter yesterday.
A set is a container, an empty string (ε or nothing) is an element. A set with nothing inside is not empty, because there is nothing inside. A set is empty (∅) if it does not have anything inside.
In python:
$ python >>> nothing='' >>> set=[nothing] >>> set [''] >>> set.append('') >>> set ['', ''] >>> set.remove('') >>> set [''] >>> set.remove(nothing) >>> set [] >>> emptyset=[] >>> emptyset []
Doing nothing and not doing anything are two different things.

NB: the feline abuse is intentionally left for simplicity and modularity.
Let’s calculate the amount of lines, containing the word “extended” in */*.conf files:
egrep -c extended */*.conf |
awk 'BEGIN {FS=":"; sum=0;}{sum +=$2} END {print sum}'
BTW, using awk alone is slower:
time awk 'BEGIN {sum=0;}/extended/{sum++} END {print sum}' */*.conf
110653
real 0m0.94s
user 0m0.91s
sys 0m0.01s
time egrep -c extended */*.conf |
awk 'BEGIN {FS=":"; sum=0;}{sum +=$2} END {print sum}'
110653
real 0m0.13s
user 0m0.10s
sys 0m0.02s
fgrep is slower than egrep:
time fgrep -c extended */*.conf |
awk 'BEGIN {FS=":"; sum=0;}{sum +=$2} END {print sum}'
