I want to write a script that searches some directory for specific files and then performs action with it. I managed to write a script, but I cannot find how to disable all but echo messages from script Lets say my script is:
Code:

I have a problem with booting my Ubuntu System.I have installed the new version of Ubuntu(11.04) next to Windows XP on my PC. When I restarted my PC I have selected "Ubuntu" from the boot menu. When I did that following massage arrived at my screen:"GNU GRUB version 1.99"rc1-13ubuntu3Minimal BASH-like line editing is supported. For the first word, TAB lists possible command complections. Anywhere else TAB lists possible device or file complectionsgrub> _"

I can't even open firefox because I don't have enough space
I found it , it was .xsessions-errors
when I try to transfer data from my laptop to the desktop using SSH I get the following massage:

Are you sure you want to continue connecting (yes/no)? I wonder is it normal massage or is there something not good?

if I'm posting to the wrong forum. Be so kind to tell me where to better ask this question, as I'm really not finding the right words to google for.So, I have a shell application (fdb) which is a Flash debugger. I want to run it using bash script, capture it's output and pass it the commands (it can read from STDIN). The reason I want to do so is that Flash Builder (the IDE for Flash development) is plain stupid when it comes to compilation, and it won't allow me to compile any file in the project... so, I found out that I can make Eclipse to run an external tool. This external tool is my *.sh file whichches the compiler, and then it launches the debugger.The Eclipse console can display the compilation results, or errors. When I run the debugger it can even pass the input from Eclipse console to the debugger, however, the output from the debugger isn't shown.

View 3 Replies View RelatedNow, I have one script called "defcon" defcon gets the current DEFCON level and outputs it using echo.
Code:
#!/bin/bash
DEFCON=`curl -s http://members.tripod.com/~Swat_25/defcon.html | sed -n '/^$/!{s/<[^>]*>//g;p;}' | sed '/^$/d' | grep '[12345]$'`
echo "The current DEFCON level is $DEFCON"
The second script ("tweet") updates my twitter account.
Code:
#!/bin/bash
curl -s -u USER:PASS -d status="$@" http://twitter.com/statuses/update.xml > /dev/null
What I want to do is be able to update my twitter account with the current defcon status (this is really more of a learning thing than something I actually want to be doing). The original script for tweet replaced $@ with $1, but if I use:
tweet `defcon`
it only uses the first word in the string, similarly if I used $2 or $3.So I changed it to $@. The normal function still works, but typing:
tweet `defcon`
updates twitter with nothing.
EDIT I should mention the /dev/null is there to catch the output of curl, otherwise it won't run silently. It still updates twitter normally with the send to /dev/null
I would like to compare the (screen) output of one bash script with the (screen) output of another bash script to ensure the output is exactly the same.The reason for this is that I am receiving a consolidated data feed from an IP address and have moved some of the data feed to a 'new' source IP address. I will turn off the feed from the original once satisfied that the new is receiving the same data. The format of the output from the scripts are exactly the same.

I have taken into count spacing of functions as a reason for not working. Can you get this function to work on your machine?
quickfind () { find . -maxdepth 2 -iname "*$1*" }

quickfind () { f

I've shell bash file script and I want to save the output into a txt file.I Know ./bash.sh > output.txt will save the result into a file but i want to add something into a bash file and then when the bash file process completed, it save the result into a file and I don't want that overwrite the output into the old file, I want each time i run it, it save the result into a new file.
View 6 Replies View RelatedFor example,I have three paragraphs,as following:
I want to output it as following:
I have to save the result of ssh/grep into a file to keep the eol ("/n"):
ssh $SSH_OPTIONS $USER@$NODE "cd $LOG_DIR; grep -h '$pattern' log.*" > $file
So that when I grep on the local file again later, it can be printed out with original log lines. Otherwise, the log lines will be dropped and lines becomes concatenated into a single line, e.g., if I rewrite the script in this way, echoing the $result is not a good idea..
result=`ssh $SSH_OPTIONS $USER@$NODES "cd $LOG_DIR; grep -h '$pattern' log.*"`
is there some workaround that I can save it to a variable rather than file but still keep the eol? That will simplify my script and don't need to do all those I/Os!
I have a bash script that calls a java class method. The method returns a string to the linux console when run independently. how can I assign the value from the java method to a variable in a bash script?running the script: java -cp /opt/my_dir/class.method [parameter]
output: my_string if added in a bash script:
read parameter
java -cp /opt/my_dir/class.method [parameter] | read the_output
echo $the_output
the above doesnt work, I also tried unsuccessfully:

I am trying to process a column separated data file, with a few bash command. For example, I have
Code:
file1 aaaa yes
file2 aaaa no
file3 bbbb yes
Let say I want to create new file with the output of first column and do something else with the output of 3rd column. Of course there are many ways to process this data file, but I wish to know by using awk, how could I do it. I'm trying:
Code:
awk '{system("touch $1")}' datafile
but the shell command will not able to get the awk '$1' output. How do I get this done ? And for another question, if the data file contains the variable name of a shell variable, how could I make use of it during a awk output ? For example I have a datafile1:
Code:
server1 yes
server2 no
And in another server declaration data file, I got this datafile2:
Code:
server1=xxx1
server2=yyy1
And in my awk script, I want to achieve something like (the syntax is definitely wrong, just to demonstrate what I assume it will like):
