2. MAKE TERMINAL BETTER

-----------------------------

alias cp='cp -iv' # Preferred 'cp' implementation alias mv='mv -iv' # Preferred 'mv' implementation alias mkdir='mkdir -pv' # Preferred 'mkdir' implementation alias ll='ls -FGlAhp' # Preferred 'ls' implementation alias less='less -FSRXc' # Preferred 'less' implementation cd() { builtin cd "$@"; ll; } # Always list directory contents upon 'cd' alias cd..='cd ../' # Go back 1 directory level (for fast typers) alias ..='cd ../' # Go back 1 directory level alias ...='cd ../../' # Go back 2 directory levels alias .3='cd ../../../' # Go back 3 directory levels alias .4='cd ../../../../' # Go back 4 directory levels alias .5='cd ../../../../../' # Go back 5 directory levels alias .6='cd ../../../../../../' # Go back 6 directory levels alias edit='subl' # edit: Opens any file in sublime editor alias f='open -a Finder ./' # f: Opens current directory in MacOS Finder alias ~="cd ~" # ~: Go Home alias c='clear' # c: Clear terminal display alias which='type -all' # which: Find executables alias path='echo -e ${PATH//:/\n}' # path: Echo all executable Paths alias show_options='shopt' # Show_options: display bash options settings alias fix_stty='stty sane' # fix_stty: Restore terminal settings when screwed up alias cic='set completion-ignore-case On' # cic: Make tab-completion case-insensitive mcd () { mkdir -p "$1" && cd "$1"; } # mcd: Makes new Dir and jumps inside trash () { command mv "$@" ~/.Trash ; } # trash: Moves a file to the MacOS trash ql () { qlmanage -p "$*" >& /dev/null; } # ql: Opens any file in MacOS Quicklook Preview alias DT='tee ~/Desktop/terminalOut.txt' # DT: Pipe content to file on MacOS Desktop

cdf: 'Cd's to frontmost window of MacOS Finder

------------------------------------------------------

cdf () {
    currFolderPath=$( /usr/bin/osascript <<EOT
        tell application "Finder"
            try
        set currFolder to (folder of the front window as alias)
            on error
        set currFolder to (path to desktop folder as alias)
            end try
            POSIX path of currFolder
        end tell

EOT ) echo "cd to "$currFolderPath"" cd "$currFolderPath" }

extract: Extract most know archives with one command

---------------------------------------------------------

extract () {
    if [ -f $1 ] ; then
      case $1 in
        *.tar.bz2)   tar xjf $1     ;;
        *.tar.gz)    tar xzf $1     ;;
        *.bz2)       bunzip2 $1     ;;
        *.rar)       unrar e $1     ;;
        *.gz)        gunzip $1      ;;
        *.tar)       tar xf $1      ;;
        *.tbz2)      tar xjf $1     ;;
        *.tgz)       tar xzf $1     ;;
        *.zip)       unzip $1       ;;

        *)     echo "'$1' cannot be extracted via extract()" ;;
         esac
     else
         echo "'$1' is not a valid file"
     fi
}

---------------------------

4. SEARCHING

---------------------------

alias qfind="find . -name " # qfind: Quickly search for file ff () { /usr/bin/find . -name "$@" ; } # ff: Find file under the current directory ffs () { /usr/bin/find . -name "$@"'' ; } # ffs: Find file whose name starts with a given string ffe () { /usr/bin/find . -name ''"$@" ; } # ffe: Find file whose name ends with a given string

spotlight: Search for a file using MacOS Spotlight's metadata

-----------------------------------------------------------

spotlight () { mdfind "kMDItemDisplayName == '$@'wc"; }

---------------------------

5. PROCESS MANAGEMENT

---------------------------

findPid: find out the pid of a specified process

-----------------------------------------------------

Note that the command name can be specified via a regex

E.g. findPid '/d$/' finds pids of all processes with names ending in 'd'

Without the 'sudo' it will only find processes of the current user

-----------------------------------------------------

findPid () { lsof -t -c "$@" ; }

memHogsTop, memHogsPs: Find memory hogs

-----------------------------------------------------

alias memHogsTop='top -l 1 -o rsize | head -20'
alias memHogsPs='ps wwaxm -o pid,stat,vsize,rss,time,command | head -10'

cpuHogs: Find CPU hogs

-----------------------------------------------------

alias cpu_hogs='ps wwaxr -o pid,stat,%cpu,time,command | head -10'

topForever: Continual 'top' listing (every 10 seconds)

-----------------------------------------------------

alias topForever='top -l 9999999 -s 10 -o cpu'

ttop: Recommended 'top' invocation to minimize resources

------------------------------------------------------------

Taken from this macosxhints article

------------------------------------------------------------

alias ttop="top -R -F -s 10 -o rsize"

my_ps: List processes owned by my user:

------------------------------------------------------------

my_ps() { ps $@ -u $USER -o pid,%cpu,%mem,start,time,bsdtime,command ; }

---------------------------

6. NETWORKING

---------------------------

alias myip='curl ip.appspot.com' # myip: Public facing IP Address alias netCons='lsof -i' # netCons: Show all open TCP/IP sockets alias flushDNS='dscacheutil -flushcache' # flushDNS: Flush out the DNS Cache alias lsock='sudo /usr/sbin/lsof -i -P' # lsock: Display open sockets alias lsockU='sudo /usr/sbin/lsof -nP | grep UDP' # lsockU: Display only open UDP sockets alias lsockT='sudo /usr/sbin/lsof -nP | grep TCP' # lsockT: Display only open TCP sockets alias ipInfo0='ipconfig getpacket en0' # ipInfo0: Get info on connections for en0 alias ipInfo1='ipconfig getpacket en1' # ipInfo1: Get info on connections for en1 alias openPorts='sudo lsof -i | grep LISTEN' # openPorts: All listening connections alias showBlocked='sudo ipfw list' # showBlocked: All ipfw rules inc/ blocked IPs

ii: display useful host related informaton

-------------------------------------------------------------------

ii() {
    echo -e "\nYou are logged on ${RED}$HOST"
    echo -e "\nAdditionnal information:$NC " ; uname -a
    echo -e "\n${RED}Users logged on:$NC " ; w -h
    echo -e "\n${RED}Current date :$NC " ; date
    echo -e "\n${RED}Machine stats :$NC " ; uptime
    echo -e "\n${RED}Current network location :$NC " ; scselect
    echo -e "\n${RED}Public facing IP Address :$NC " ;myip
    #echo -e "\n${RED}DNS Configuration:$NC " ; scutil --dns
    echo
}

---------------------------------------

8. WEB DEVELOPMENT

---------------------------------------

alias apacheEdit='sudo edit /etc/httpd/httpd.conf' # apacheEdit: Edit httpd.conf alias apacheRestart='sudo apachectl graceful' # apacheRestart: Restart Apache alias editHosts='sudo edit /etc/hosts' # editHosts: Edit /etc/hosts file alias herr='tail /var/log/httpd/error_log' # herr: Tails HTTP error logs alias apacheLogs="less +F /var/log/apache2/error_log" # Apachelogs: Shows apache error logs httpHeaders () { /usr/bin/curl -I -L $@ ; } # httpHeaders: Grabs headers from web page

---------------------------------------

9. REMINDERS & NOTES

---------------------------------------

remove_disk: spin down unneeded disk

---------------------------------------

diskutil eject /dev/disk1s3

to change the password on an encrypted disk image:

---------------------------------------

hdiutil chpass /path/to/the/diskimage

to mount a read-only disk image as read-write:

---------------------------------------

hdiutil attach example.dmg -shadow /tmp/example.shadow -noverify

mounting a removable drive (of type msdos or hfs)

---------------------------------------

mkdir /Volumes/Foo

ls /dev/disk* to find out the device to use in the mount command)

mount -t msdos /dev/disk1s1 /Volumes/Foo

mount -t hfs /dev/disk1s1 /Volumes/Foo

to create a file of a given size: /usr/sbin/mkfile or /usr/bin/hdiutil

---------------------------------------

e.g.: mkfile 10m 10MB.dat

e.g.: hdiutil create -size 10m 10MB.dmg

the above create files that are almost all zeros - if random bytes are desired

then use: ~/Dev/Perl/randBytes 1048576 > 10MB.dat
