General :: Using Shortcuts/alias Inside A Bash Command?

Jan 28, 2010

I know that using alias I can run a whole command with a shortcut. But my requirement is to use parts of a long command and in between I have to pass some user defined values.
E.g. Suppose I have to routinely copy a directory to another remote directory on a remote machine.The remote machine name is quite long as well as the directory path to which I want to copy the files into.So the command to do scp would look like this[URL]Now I want to do some sort of aliasing (say "ecp") so that I just need to pass the source_directory name and the ecp command and do my job

Programming :: Command Line Works - Won't Work From Inside Bash Script

Feb 16, 2011

Writing script to create backup of file by adding datetime to file name. Basically test for file presence if there, cp with datetime then rm original cp works fine from command line but get cannot stat `full path to file': No such file or directory

Code:

Here are the errors: cp: cannot stat `~/html/CVP_dadamail/.dada_files/.logs/errors.txt': No such file or directory rm: cannot remove `...': No such file or directory

The for statement is a placeholder as I have same file to backup out of several directories. using "bash -x scriptname" -OR- inserting echos, I can see I've constructed the strings properly. Believing it might be related to the hidden directories, I tried setting the shopt "glob" options to no avail.

Ultimately I'll add the other directories to the for loop and then run this from a cron job, so if you see potential pitfalls knowing I'm headed in that direction...believe construct would be

General :: Bash Function/alias For Package Managers?

Jul 6, 2010

I have packer installed for AUR packages, but I want to be able to use the pacman command for both. I think I will need a function for this -- what I mean is that whenever I use pacman, it will try using packer and if that fails (invalid option) it will use pacman-color. It could also decide which program to use based on the arguments. I can't just use packer (alias pacman='sudo packer') because packer doesn't have some options like -R to remove packages. I want to always use it to install and upgrade packages however, because It can install from the default repositories as well as AUR.

Does someone know how to accomplish this, or could point me in the right direction? I'm new to bash scripting. error (e.g. pacman -V prints packer: Option '-V' is not valid.).

General :: How To Alias A Command For Sudo

Sep 25, 2010

I have an alias that I would like to use both as a regular user and as root, via sudo. Specifically, it is this:

alias rm=trash This works fine as a normal user, and it works fine when I use sudo -i to get a root shell prompt, but if I use sudo rm, the alias does not apply. So where do I need to put my alias so that it works in one-off sudo commands?

General :: Setup An Alias Or Shortcut To Do The *nix Find Command?

Apr 5, 2011

When at the command line, I find that I have to type out this command very often: find . -iname "*php" -exec grep -H query {} ; I'd love to set up an alias, script, or shortcut to make it work easier. I would like to do something like: mysearch query ("*php") (.) It would be great if the command could accept three arguments, in reverse order:

query string, file name expression, directory If the second two arguments were omitted they would default to not being included, and the current directory. Finally, the icing on the cake would be that if additional variables were included (4th, 5th, 6th...) they would be injected as additional arguments for the find command (like I could say -type d) at the end. Attempted code I tried the example below, but I'm still having trouble setting default values. What am I doing wrong?

#!/bin/bash
c=${param1+.}
b=${param2+*}
a=${param3+test}
find $c -iname $b -exec grep -H $a {} ;

General :: Alias A Device For The Mount Command In RedHat 9?

I have a program which mounts /dev/sdb1 for which I lack the source code. This device does not exist on my RedHat 9 system and I want to create /dev/sdb1 such that it's an alias for /dev/hdb1 Can I do this? with MAKEDEV?

I need to have an alias which will allow it to mount, not create a symbolic link to an already mounted directory. i.e. 'mount /dev/sdb1 /mnt/harddrive' should actually mount /dev/hdb1

General :: Run Command As Root Inside Script?

Sep 4, 2009

I am running a shell script using a non root user. Somewhere down in the script, I'll have to call some script to be executed as su (or a user with more privileges than the one running the original script). So if i put a line in the script as:

Code:

su - root -c /root/roleScripts/assignRoles.sh

Then when running the command, it will prompt me for root password(because the current user has lower privileges than the user requested. Suppose I want to pass this password as an argument to the original script, so that it doesn't prompt me for password later on, what is the way? Can I switch user passing the password and run a command?

General :: Execute Command Inside First Directory Of Each Matched Result?

Aug 8, 2011

I am working at a client who has a project where code is a mixture of different source control systems. So a layout might be like this

project/a/.svn
/a/subfolder/.svn
/b/.hg
/c/subproject/.svn
/d/.hg

So I am trying to put together a simple command that when executed from the project folder will run the appropriate hg/svn command in each project i.e:

[Code]...

Since the client has many such projects, Instead I am looking for a solution similar to find -exec where the svn/hg commands are automatically executed on each first level of match (i.e. svn up is run in the project/a folder but not in project/a/subfolder). How can such a command be constructed ?.

General :: Function Having Background Process Inside Command Substitution

Oct 5, 2010

The first call to "somefunction" works as expected. The function prints "endfunction" and a process in background sleeps 30 seconds. In the second call I thought it should work in the same way, but the script sleeps 30 seconds before it prints "endfunction".Does someone know the reason of this behavior? Is there another way to do a command substitution of a function that has a background process without have to waiting for that process?

Fedora :: Bash Function Alias To Recursively Grep Current Directory?

Feb 14, 2011

This should be a simple thing to accomplish, but I can seem to figure it out. Essentially, I want to have a bash alias or function that will let me recursively grep the current directory. A while back I added this to my .bashrc:

Code:

alias rg="grep -r --exclude=*/.svn/* --exclude=*.swp"

This works fine, (and also ignores any svn and vim swp files), and I can call it like:

Code:

rg foo *

However, 99.999% of the time, I am only interested in searching in the current directory, so the "*" is a bit redundant. Also, I would say 5-10% of the time, I am typing faster than thinking and forget the "*", so grep just sits there trying to read from stdin. It's a pretty minor thing, but ideally I'd like to be able to just type:

Code:

rg foo

I've tried creating a function to handle this:

Code:

function rg(){
grep -r --exclude=*/.svn/* --exclude=*.swp $1 *
}

but it behaves exactly the same as the alias above. escaping the "*" with 's doesn't work, and neither does trying `pwd` (or even a hard-coded path) in its place.

General :: Setup An "alias" Command For IDL?

Jan 25, 2011

I have installed IDL 7.1 on my Ubuntu 9.10. And now the instruction says that I should set up an "alias" for it.I do not know what to write in my "bashrc" as an alias for IDL.
These are the place of the executable command of IDL:

/IDL/idl-7.1/bin/idl
AND
/IDL/idl-7.1/bin/idlde

Note that "idl" and "idlde" are the executable files which run the program by typing them in Terminal. I would be very grateful if anyone could help me in how to write an "alias" for my IDL.

General :: Bash Command History Update Before Execution Of Command

Jun 7, 2010

Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).

I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?

Programming :: Bash Script - Sending Shortcuts To Firefox

Aug 26, 2010

When I attempt to extract some webpages there are far too many jscript functions and html encodings. Hence, I can manually search the page, perform select all (^A), copy (^C) it, open a prepared file (^O), but cannot figure how to paste it (&V). I want to do this from a bash script. I know how to do the search. Now how do I send these shortcuts (especially ctrl-C) to Firefox. Once I have the page copied to the clipboard, I think I can figure out how to open a file and save the clipboard to a file using bash script on the Linux side. How do I send shortcuts to Firefox? Is this done with the hex equivalent of the keystrokes?

Programming :: Awk Commands Inside Of A Bash Script ?

May 4, 2011

im pretty sure this is a remedial task for many of you but im having an issue with arrays from a shell script being accessed in an awk command. im pretty good with shell scripting but i am embarrassingly unfamiliar with awk. so here's the meat of the script...


Code:

I am trying to take an input file of ip addresses and corresponding netmasks and put it into a format to be loaded onto a juniper switch. the result should look something like this.. x.x.x.x/netmask using the cidr notation. no matter what subnet is provided though, /32 always gets appended to the end of the ip even when it should be /16, /24, etc... also, the cisco part works fine so that doesnt need any attention.
