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 ../../../../.."

Advanced C++ - Stack unwinding

Stack unwinding is normally a concept of removing function entries from call stack (also known as Execution stack, Control stack, Function stack or Run-time stack). Call Stack is a stack data structure that stores active functions' addresses and helps in supporting function call/return mechanism. Every time when a function is called, an entry is made into Call stack which contains the return address of the calling function where the control needs to return after the execution of called function. This entry is called by various names like stack frame , activation frame or activation record. With respect to exception handling , stack Unwinding is a process of linearly searching function call stack to reach exception handler. When an exception occurs, if it is not handled in current function where it is thrown, the function Call Stack is unwound until the control reaches try block and then passes to catch block at the end of try block to handle exception. Also, in this proc...

C++ Multithreading - Race conditions

In the previous C++ Multithreading article I presented you how to pass parameters between threads. Take a detail look on the output of that example once again: In the first line of that output you can notice that output text from two threads is mixed. You are probably wondering why it happens? It is because we are not protecting resources which are shared by two threads (in this example cout stream is shared in both threads) which causes multithreading's phenomenon called race condition . Because threads switching and accessing to shared resources are managed by operating system we do not know when std::cout stream will be accessed by main thread and when it will be accessed by second thread. Therefore in the previous article I mentioned that output of the example can be little different on your computer than my output example. What's more it is possible that this output will be different for few consecutive invoking of the example on the same machine. It is beca...
