Bash - useful bash aliases which I use in my daily work

~/projects/CppAdventureExamples/bash/aliases.html Bash alias is abbreviation of one terminal command (usually long command) using other terminal command (usually much shorter command). We can define aliases in bash dot files (ex. ~/.profile file).

Example of bash alias:
alias i="sudo apt-get install"
Then we can install 'vim' package using 'i' alias this way (it works of Debian-based systems):
i vim 
Today I would like to present few useful bash aliases which I use in my daily work.
You can paste below aliases into your ~/.profile file (or ~/.bashrc) if you recognize them useful for you.
Enjoy!
#==================================================================
# Listing aliases 
alias ll="ls -lah"
#list only directoriesj
alias lsd="ls -lF ${colorflag} | grep --color=never '^d'"
alias sl='ls'

#==================================================================
#filter selected app from running commands 
alias pg="ps aux --sort=start_time | grep"
#list all apps runned by me and sort by start time
alias pm="ps aux --sort=start_time | egrep '^$USER'"

#==================================================================
# BUILD ALIASES
# speed up make + make install using all available CPU cores
alias mi="make -j`nproc` && sudo make -j`nproc` install"

#==================================================================
# OTHER ALIASES
# show last notes to syslog file quickly 
alias lg="tail -f /var/log/syslog"
# speed up wget in parallel (on 16 threads)
alias wgetp="aria2c -x 16 -s 16"
#generate 12-character long password 
alias passgen="strings /dev/urandom | tr -cd '[:alnum:]' | fold -w 12 | head -n 1"
# retart apache2 server
alias aprst="sudo /etc/init.d/apache2 restart"
# show open ports
alias ports='netstat -tulanp'
# ps 10 memory and cpu consuming processes 
alias psmem='ps auxf | sort -nr -k 4 | head -10'
alias pscpu='ps auxf | sort -nr -k 3 | head -10'

alias k="sudo kill"
alias ka="sudo killall"

#==================================================================
# Navigation shortcuts
alias ..="cd .."
alias ...="cd ../.."
alias ....="cd ../../.."
alias .....="cd ../../../.."
alias ......="cd ../../../../.."

QT - foreach algoriithm with const references performance improvement

Today I would like to show you optimal way of using foreach QT algorithm . I will show you why we should pass elements of foreach algorithm by const reference instead of passing them by value. Let me explain it on the below example: Output of this example is: In point I we are creating 3 objects of MyClass class and push them to myClasses QList element. In point II we are using QT foreach algorithm to invoke getValue() method for each object from myClasses list. As you can see on output text for that part of code we are invoking copy constructor before and destructor after invoking getValue() function. It is because we are passing each myClasses list element to foreach algorithm by value. Therefore we are copying that element at the beginning of foreach loop step and removing them (destructing) at the end. This is inefficient solution, especially when class of object being copied is big. It decreases performance. of our application. Solution for that i...

C++ in 2014 - Predictions

Today I would like to share with you interesting article about prediction of development C++ programming languages (and its well-known frameworks and libraries) in 2014. It is written by Jens Weller and I think it is very interesting for every C++ programmer and user. You can open this article by clicking on the image below: Enjoy!
