when I am running the script below,it performs on whatever logfile u type ,i.e, ./scriptname logfilename.But how do I convert it into a function and then call it from another script.I mean how do I prompt the user to enter a logname and then capture the name in the function and when calling this function from another script how do I pass the parameter.
View 3 RepliesI want to have a choice or more preferable pass shell as command line argument when I ssh to an linux account.i.e. If John logs in to account "zzz" on server "abc", by default definition of account "zzz" n server "abc" he get csh.But Sally desires that when she logs in to account "zzz" on server "abc", she needs the login shell to be ksh,and Rick wants bash when he logs in to account "zzz" on server "abc".What is the most non-intrusive / easiest way to achieve this? Each user can set their preference on ssh command line or create a simple alias by each shell, but not sure how to do this.

I then installed unbuntu on the sata along with debian but can't access unbuntu. when I tryed to install grub it error'd out so I bypassed that and finished the install.

[code]...
I am attempting to script some tasks I have to do, but I have no control over one of the scripts I have to use... and they output all kinds of useless things on the screen. My goal is simple: Capture all output from their scripts, and create a progress line that only shows the most recent output from their stuff. So, here was my first solution; a file I called "spin":
Code:
#!/bin/bash
spinX(){
PROC=$1
STRT='date "+%s"'
while [ -d /proc/$PROC ];do
last3=" 'getLine $2' "
To use it, you pass it a process ID and a file that contains the output from that process. As the process continues, a kurby dances on the screen (To let you know that the process has not hanged), and the tail of the output is shown (To let you know what it is doing). When the process ends, the kurby stops dancing and the time it took is displayed.
And here is the file I call "noise":
Code:
#!/bin/bash
while [ i -lt 100 ];do
i=1
echo "Look at me count!$"
sleep 1
let "i=$i+1"
done
This does nothing but create random output, for testing. It counts from 1 to 99 on the screen. To run my test, I do the following:
Code:
(noise) &>tmp.txt & spin $! tmp.txt
It works relatively well, but it is messy. I don't like creating a temp file, and I don't like the messy syntax for calling my program. I decided that I would rather move everything into the spin program, to make using it less messy:
Code:
#Spin Psuedo code
#$1 = command I am about to run
(exec $1) &>tmp.txt & spinX $! tmp.txt
By executing the process inside of the spin code, I can get rid of the tmp file later on without changing a lot of scripts (Or move it, or whatever). I can also call it by passing the command to the script, which I find more elegant.
So here is what I would like to know:
1) If possible, I would love to get rid of the tmp file all together, and store the most recent line of output from script 1 into a variable that script 2 can print out instead... is it possible?
2) How can I run a random command that is passed as an argument? Basic ones work fine, but anything with a pipe fails me.
Example of a script:
Code:
#!/bin/bash
#myEcho.sh
echo;echo "Recieved command: ";echo $1;echo;
echo "Attempting to run command: ";echo
exec $1
Example code for passing commands to script:
> myEcho.sh "ls -al" #works
> myEcho.sh 'ls -al' #works
> myEcho.sh "ls -al|grep *.sh" #fail
# Output:
#ls: invalid option -- |
#Try 'ls --help' for more information.
> myEcho.sh "ls -al|grep "*.sh"" #fail
# Output:
#ls: invalid option -- |
#Try ls --help' for more information.
> myEcho.sh 'ls -al|grep *.sh' #fail
# Output:
#ls: invalid option -- |
#Try 'ls --help' for more information.

I have a backup schedule running a full backup everyday. I'm using webmin to manage these backup now. The problem is when the dump command sends a prompt asking if we want to rewrite the tape, Webmin does not display this prompt and we end up having to terminate the backup -> erase the tape(which takes a long time) and then run the backup again.I was wondering if there is a technique that could be used to pass "Yes" as a parameter to the dump command, much like in windows? or if there is a more efficient way of getting this done.

I have access to backup server via rsync protocol (only rsync, nothing else). Now, I want to fetch file from there (which is .tar.gz) and pass it directly to tar command, without saving the archive in local filesystem. To visualize, with ssh access I could:
ssh remote_host cat backup.file.tar.gz | tar xzf - And I will get uncompressed backup locally, without actually storing .tar.gz on local machine. Is it possible to achieve when using rsync?

I'm running Red Hat Linux 5.4 on HP DL580 server with 16 processors and 64 GB of RAM. I'm connecting to the server remotely through SSH. after entering the password, it takes time to return the command line, if I click ctrl+c during this time, I'll have the command line prompt but not the correct bash prompt (I have to run bash to pass to my correct prompt).I tried to install Apache on the server, ./configure took 4 hours to finish instead of 1 or two minutes, Oracle installation same behavior. Server Disks are mirrored using RAID controller.
View 6 Replies View RelatedI've written myself a linux program "program" that does something with a regular expression. I want to call the program in the bash shell and pass that regular expression as a command line argument to the program(there are also other command line arguments). A typical regular expression looks like "[abc]_[x|y]".Unfortunately the characters [, ], and | are special characters in bash. Thus, calling "program [abc]_[x|y] anotheragument" doesn't work. Is there a way to pass the expression by using some sort of escape characters or quotation marks etc.?
(Calling program "[abc]_[x|y] anotheragument" isn't working either, because it interprets the two arguments as one.)

After contracting malware on Vista i decided to switch over to Linux and chose to start of with Ubuntu because of the graphical interface. that being said, you have no doubt inferred that i have no coding experience. basically i was hoping to find some nice tutorials and sites for Ubuntu. Also, i did downloaded the suggested programs and patches but im still experiencing problems with Adobe,flash, and and opening .exe files. for the latter, when i click on .exe files it is equivalent of using explorer on windows so i was wondering how to use the command prompt to open them. supposedly linux is susceptible to malware so if you could please suggest a anti -malware program.

I was curious if I would be able to view cookies from a command prompt when ssh'd into a machine. On a test machine running fedora 13, I found that the cookies were stored in a cookies.sqlite. I made sure that all instances of Firefox was closed and attempted to view the file running the following command
sqlite3 cookies.sqlite
It loaded but I was unable to run view any of the information because the database was locked? There were no instances of Firefox running and I check to make sure there were no services of Firefox running as well. Am I doing something wrong? Is this not the correct way to view cookies from the command line ? I have tried google searches and has since been unable to come up with anything.
