On my Mac laptop I have these as the twenty most used commands:
overkill(shand)$ history | awk '{a[$2]++} END{for(i in a){print a[i] " " i}}' | sort -rn | head -20
847 ls
646 cd
332 svn
317 sudo
295 ping
185 port
176 rm
174 ssh
159 scp
159 ifconfig
155 vi
148 host
139 man
138 less
119 p
114 find
101 l
95 open
90 echo
86 pass
And on my Debian Linux server I have this:
maxx(root)# history | awk '{a[$2]++} END{for(i in a){print a[i] " " i}}' | sort -rn | head -20
1610 ls
1052 cd
635 less
460 grep
340 sudo
322 vi
321 l
311 rcsedit
216 for
201 host
195 cat
166 mkroot
154 tail
154 mv
152 rm
139 svn
127 cp
123 apache2ctl
118 find
115 apt-cache
Most of this is pretty straight forward the only interesting ones are:
- "port" is the command line utility from MacPorts for managing packages
-
"l" is the standard "ls -l" alias which everybody has:
l() { ls -l $* | more; } -
"p" is a slightly fancy alias which basically does "ps -efww | grep" but with some cross platform smarts:
p() { if [ $LINUX ]; then OPTIONS="-efww"; elif [ $IRIX ] ; then OPTIONS="-ef"; elif [ $DARWIN ]; then OPTIONS="-Ajww"; fi if [ ! $1 ]; then ps ${OPTIONS} | more else ps ${OPTIONS} | grep -i $1 | more fi; } -
"rcsedit" is the standard sysadmin wrapper script for making editing files with RCS easy.
-
"mkroot" is what I use to become root and keep my personalised environment (because modifying root's environment is a bad thing):
alias mkroot='sudo bash --rcfile ~/.bash_profile' -
"pass" is a script I use for managing my passwords in a GPG encrypted file
Though it doesn't make this list, "spex" is another great alias which I use for remembering obscure and useful command lines.
