Преименуване на фаилове наведнъж.

touch file{1..10} - file1 file2 ...
rename 's/$/.bak/g' * - добавя .bak на края
rename 's/.bak/.jpg/g' *

Ако има едновременно: папки и фаилове.
find -type f | rename 's/$/.bak/g'

За да се запази оригинала:

sed -i.bak -e 's/$/.bak/g' *

Сортиране колона в ред awk.

apache е за пример!

top -b -n1 | grep apa | awk '{print $1}' | sort | awk 'BEGIN {ORS = ","} {print }' \

Ползва фонетика и се сменя с alt + shift

Firebird SS amd64

Инсталцията от хранилищата на ubuntu и debian не работи.
Инсталира се xinetd, и се сваля от официялната страница на firebird:

Вече firebird-а се намира в /opt, a не в /etc
netstat -na | grep 3050 - работи.

php send mail

Е така и не успях да го накарам wamp да прати email, през Windows, но с linux няма проблем с тези настройки :)

sudo apt-get install ssmtp

mailhub=smtp.gmail.com:587

AuthUser=<YOUR-EMAIL>@gmail.com
AuthPass=<YOUR-PASSWORD>

nano php.ini

sendmail_path = /usr/sbin/sendmail -t  

Когато си забършеш /dpkg папката

sudo mkdir -p /var/lib/dpkg/{alternatives,info,parts,triggers,updates}
sudo cp /var/backups/dpkg.status.0 /var/lib/dpkg/status
apt-get download dpkg
sudo dpkg -i dpkg*.deb

Премахване на коментарите от php фаиловете в папка.

sed -i '/#.*/ d' test/*.php

-i - запазва промените
test/*.php - всички фаилове в папака test с окончание php
#.*  - трие целият ред, който започва с #

Добавяне на ред във всички записи.


sed -i '1i <?php include(header.php) ?>' test/*.php

1i - на кои ред да се добави.

Пинг на мрежа със задаване na ип-тата.

// Обработка на фаилчето
cat logping.txt | grep -B 2 "rtt min/avg/max/mdev " | grep ping | cut -d' ' -f2

print $2 - ще изпринти втората колона (първата е номера на командата).
sort - сортира записа, sort -nr - реверсивно сортиране
uniq -c - показва колко пъти е дадена командата
head - първите редове
