Here are some examples ~ where cc /usr/bin/cc /usr/bin/cc ~ which cc /usr/bin/cc and ~ which which which='alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde' /usr/bin/which ~ which where /usr/bin/which: no where in (/usr/local/bin:/bin:/usr/bin:/home/bnikhil/bin:/bin) also ~ where which which: aliased to alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde which: shell built-in command /usr/bin/which /usr/bin/which ~ where where where: shell built-in command To me it se (HowTos)

Where are aliases defined? 3 years 30 weeks ago

Hello,

Upon a fresh install of Fedora 11 (and as a Fedora n00b), I noticed there are several aliases defined for me.

Code: $ alias alias l.='ls -d .* --color=auto' alias ll='ls -l --color=auto' alias ls='ls --color=auto' alias vi='vim'

Possible Duplicate: In Bash, when to alias, when to script, and when to write a function?

If I want to make a command like gsb that will expand to something like git show-branch -a | more or something even longer, what are the pros and cons of using a bash shell alias vs making a bash script and putting it on your PATH?

Are there any performance considerations?

executing aliases from a file 43 weeks 4 days ago

hi there, i've got this alias i want assign only sometimes, and then work in the same shell with it (so when closing the shell the alias dissapears). As the alias is long, i want it to be in a executable file, so i just execute the script from a terminal and then i can access the alias from that same terminal.

In my /home/user/.bashrc file, I have those aliases to prevent mistakes:

alias rm='rm -i' alias cp='cp -i' alias mv='mv -i'

If I'm really sure of what I'm doing, I can overwrite rm and mv aliases using rm -f or mv -f, it will not ask me if I really want to overwrite files.

The problem, is that it doesn't work for the cp command, using cp -f will still ask me a question.

Is this normal?

Let's say i have the following alias in bash - alias ls='ls --color=auto' - and i want to call ordinary ls without options. Is the only way to do that is to unalias, do the command and then alias again? Or there is some nifty trick or workaround?

Tree as alias command 22 weeks 1 day ago

Hi, I have this command:

Code: ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/  /' -e 's/-/|/' Works nicely to show the current file structure as a tree.

I'd like to have it as an alias in '' but doesn't work just like that and I can't fix it with backslashes:

Code: alias tree='?' Can someone help? Thanks

HISTIGNORE variable is set to:

export HISTIGNORE="&:ls*:reboot:pwd:exit:clear:[ \t]*"

I have couple of Alias set. One of them is

alias todo='emacs ~/Dropbox/Documents/todo.txt'

None of them shows up in history. Not that I want them to show up in history, but what baffles me is, why the hell they do not show up in history.

Problems with bash scripting 1 year 9 weeks ago

I'm trying to setup an alias in my .bashrc file, but it's not working as expected.

I have this alias which works:

alias lolcat='python /home/martyn/Dropbox/Applications/Scripts/logcat-viewer/unixcoloredlogcat.py'

and I normally use this command as such:

adb logcat SomeValue:* *:e | lolcat

But I want to put that in to an alias so that I can write:

logcat SomeValue

but my alias below isn't

If one:

$ find -name 'some expression' -type f > newfile

and then subsequently wants to create an alias file from each pathname the find command retrieved and the > placed within 'newfile', how would one do this? Ideally, the newly created alias files would all be in one directory.

I am on a Mac OS X 10.7.
