We're going to be doing a rather large server deployment, and using the provisioning system we have in place there is no current way to just "copy" a file over to the servers. All files/scripts have to be run from the provisioning server.Due to network constraints, the provisioning system can't run a script we need to run (requires certain network assets to complete, but as soon as we modify the network settingshe provisioning system loses access to the server and can't run the script). So,our network configuration script to create the other script on the server in /root when it runs.My original method was to do something along the lines of:
I have a simple log file which is very messy and I need it to be neat. The file contains log headers but are all jumbled up together thereforeI need to sort the log files according to the log headers. There are no static number of lines that means that there is no fix number of lines for the each header of the text file. And I am using AWK to sort out the headers.The Log files goes something like this:

I'm not sure how to explain my situation. I would like to download the file <https://www.vmware.com/tryvmware/p/activate.php?p=free-esxi&lp=1&ext=1&a=DOWNLOAD_FILE&baseurl=http://download2.vmware.com/software/vi/&filename=VMware-VMvisor-Installer-4.0.0.Update01-208167.x86_64.iso> via the command line. I've tried a few different methods with wget, the best I get is an index.php file. I'm not at all familiar with php but a search for "wget php" yielded nothing helpful.
I am trying to write a bash script to delete a file where I know the first part of the name, but it has spaces in it. The second part of the file name is a random set of characters. I was hoping to use a wildcard for this, but I keep getting a error massage saying file or directory does not exist. This is a simplified form of my script:
Code: MYFILE=This is my file rm "$MYFILE*" The file may be something like "This is my file.123abc456.suffix"
I want to copy all files with the name XYZ* into one folder. The problem is that the files are in different subfolders and that not even the depth of the folder structure is the same for all files. Luckily, at least each file has a unique name.
Of course, I thought about the cp command but I guess the depth of the folder structure needs to be the same for this to work.
This works as expected, but I don't see neither the input nor the app output. The application is an interactive prompt written in C. When I interact manually with it, I see the prompt itself and responses to my input, but when I execute the aforementioned script I see nothing. I would like it to print the input and the output as if a real user was typing. Do you know how to achieve that?
I have a process which logs output to log.txt. If I want to see the process's status in real-time, is there a way to echo that output to stdout instead of opening the log in a text editor and constantly reloading?
I'd like a function in my .bashrc file that would allow me to pass text to it and echo the text to a specified file. I know it's simple as "echo 'text' >> file," but ideally, I would want to alias the function so I execute something like:
Code: user~ $ write 'this is a test' with "write" being the function, and 'this is a test' being echoed to the file. I hope I explained that well enough.
I would like to append text to a file. so i wrote in bashecho text >> file.confHowever it doesnt leave a new line. So i can only do this once. How do i add a new line?
I'm trying to create a shell script to take an argument and use it to name a terminal tab. So if the script's name is tabnm, tabnm "test" should rename the current tab "test"
This is my code:
#!/bin/sh echo -ne "e]1;$1a"
but when i run it I get this output:
robin@icarus $ sh tabnm.sh test -ne e]1;test
If I just run echo -ne "e]1;Testa" straight in the shell, the tab is renamed.
I want to prevent "^C" from echoing when Ctrl-C is pressed. I did "stty -echoctl" which some googling results suggested. Now it echos raw Ctrl-C characters instead of the string "^C". That's not any better since it displays some funny blocked hexadecimal in the terminal window.
Would like to know how to turn "echo" off in a shell scripting. I wrote a shell script, testing a condition, after the condition tested. On the other line I used the echo Command to echo a line, then on the other line I used the "read" command to read an input typed. The crux here is the string or line inputed is what I would like to turn off. Distro is redhat linux.
I have bash script which has lots of echo statements and also I aliased echo to echo -e both in .bash_profile and .bashrc, so that new lines are printed properly for a statement like echo 'Hello World' the output should be I even tried using shopt -s expand_aliases in the script, I am running my script as bash /scripts/scriptnm.sh; if I run it as . /scripts/scriptnm.sh I am getting the desired output.
How can i enable caps lock by using echo command. I know that by using syntax echo -e "33[3q" this only turns the capslock led to glow. but the capslock is not working i.e. the words are typed in small case only.
Then by using xmodmap command i.e. syntax xmodmap -e "remove lock = Caps_Lock" or xmodmap -e "add lock =Caps_Lock" doesn't work. On running this it shows unable to display.
Can any body tell me where can i found the source code for echo command. so that i can download it such that it can help me for further studies on echo command
I logged into my Red Hat Enterprise Linux machine at work (use it for software development) and the primary GUI does not load. Instead, widgets appeared for xclock, xterm, and Firefox. In the terminal, I start typing in commands to try to figure out what's going on, but all commands are not found except pwd and echo. I 'echo $PATH' and that returns just an empty, blank line. 'echo $SHELL' lets me know I'm using cash.
The likely cause was my attempt to install Adobe Reader Firefox plugin yesterday. After it downloaded, I ran the binary but Firefox didn't seem to recognize that I had installed it, so I went into my .cshrc file and added the adobe folder to the path. That didn't seem to work, so I gave up, deleted the binary and the folder I installed to, and removed that directory from the path in the .cshrc file. This last thing (the export PATH line in that file) I'm certain is back exactly as it was before.
I have successfully added the /bin and /usr/bin back to the path from command line via setenv PATH /usr/bin:/bin but of course it doesn't stick after reboot nor does it magically load the primary GUI. I'd rather not go through the effort of creating a ticket for our company's Global Service Desk cuz there's no telling how long that could take to resolve. In the meantime, I can't do any programming.
I faced a issue with updating a file contents with echo command which fails with error as below: echo "foo" > bar //to create a file named "bar" echo "foobar" > bar //to edit its contents
The latter fails, it prompts "File exists" i.e. ~>echo "foo" > bar ~>echo "foobar" > bar bar: File exists. ~>cat bar foo ~>
I have to run "pppd call idea" command from root shell every time to connect to internet from mobile. Now I want a script so that I just run it to connect. Something like :
#!/bin/sh echo "password" --stdin | su - pppd call idea
But its showing error that "standard in must be a tty". Why is this. Using CentOS 5.5
I am trying to figure out a totally odd behavior of the ext3 filesystem mounted in Ubuntu 9.10. There is a Korn Shell script, part of which does the following in the loop:
while ((1)); do mv dir1/file dir2; if [[ ! -r dir2/file ]]; then echo "ERROR" ls -l dir1/* dir2/* exit 1 elif echo "OK" fi done
Given that dir2/file always exists and that I do not move it asynchronously with "&", my script should never hit the "ERROR" statement. The odd thing is that it does, and quite randomly (no pattern at all). However when it does hit the ERROR case, ls -l prints that file is in dir2 and it is readable! I tried using "-e" instead of "-r" test - no luck. I never seen anything like this in 10 years of my programming experience. Same script worked fine on Fedora 11, and yet it wouldn't work on Ubuntu.
I've got a fairly complex bit of code (a for loop within a for loop) which I'm trying to execute remotely, however because of the special characters this exits without making the connection.Usually I'd do:ssh root@ipaddress "for i in `cat /etc/hosts | awk '{print $2}'`; do ping $i; done;"But given the complexity of my code this usual tactic doesn't work
