After writing a new prompt for Bash, I noticed that one character of my commands were being lost when it wrapped to the new line. Here is an image of the example (I typed 1234567890 over and over):
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.
Currently the terminal prompt looks like this:[karlis@karlis-desktop current_folder]$How can I minimize the prompt, so that it only shows $ or # without extra info in square brackets?I checked the preferences for the default Gnome-Terminal and Terminator - there are no settings for this. It is pretty hard to use terminal when working in directories with long names.
I have one account on an Ubuntu server with the correct PS1 variable and I want to make one of my other accounts on the same server have the same PS1 variable, so that my prompt on this new account (when I ssh into the machine) is the same as the original account.
Is there a way that I can pass this PS1 variable between accounts so the prompt is the same?
I have tried printing it out, copying the output, and then reassigning it to PS1 on the new account, but it just doesn't work.
I'm trying to change the bash prompt and based on the man pages $ should show a $ which changes to a # for a SU. However, this doesn't happen on my machine, it's $ for both user and SU.The line in .bashrc is:export PS1="u@h:w$"
Everytime I log into the linux server at my workplace (I use putty), I don't get the bash prompt right away. I need to execute the command 'bash' to get it. Anyway to make this automatic? e.g.
I'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.)

I have a log file that contains information like this:
---------------------------- r11141 | prasath-palani | 2010-12-23 16:21:24 +0530 (Thu, 23 Dec 2010) | 1 line Changed paths: M /projects/ M /projects/
[code]....
what i need is, i need to copy the data given between the "---" to seperate files, for, e.g. the first set of data between the "---" should be in one file and another set of data in another file.
I've written custom prompts for several boxes but this one has an error I just can't identify and need a second set of eyes to help solve it.
I've set the following as my prompt: PS1="[e[30;42m]u@h[e[0m][e[30;47m] #][e[0m][e[32;1;40m]w>[e[0m] " (hostname/un obscured & image enlarged slightly to make it easier to read.)
Everything looks fine initially as you can see here:url
1- It sets the username@host in back on green text. 2- It then changes to an off-white an prints the command number for the terminal. 3- Next, changes to a green on black font and prints the working directory. 4- Finally is prints a ">" character and a space.
The problem occurs when I try to "up arrow" to reuse and/or edit a prior command. It prints the prior command fine, but if I arrow over to edit the command sometimes the first character can not be deleted from displaying as you can see in the following composite screen-shot
url
Here I did a simple ps and piped it through grep. After getting the output, I up-arrow to repeat the command. As you can see by the second section the cursor only goes back to the "s" in ps. The "p" can not be deleted. Hitting enter just displays a new line, so the "p" was just a ghost being displayed and not really there.
I have a script almost working except for 1 thing. What I'm trying to do is read a file that has the files that need to be FTP'd using a bash script. I have everything working except the reading of the file. It works outside of the ftp script I've wrote but once I put it in the FTP script it doesn't.
Here's the Script:
#Here's where the problem is that I know of
I've been playing w/ the exclamation points to see if that could be the problem, but so far no luck.
I tried to tag late onto a question similar to mine on stackoverflow (Find Non-UTF8 Filenames on Linux File System) to elicit further replies, with no luck so far, so here goes again... I have the same problem as the OP in the link above and convmv is a great tool to fix one's own filesystem. My question is therefore academic, but I find it unsatisfactory (in fact I can't believe) that 'find' is not able to find non standard ascii characters.
Is there anyone out there that would know what combination of options to use to find filenames that contain non standard characters on what seems to be a unicode FS, in my case the characters seem to be 8bits extended ascii rather than unicode, the files come from a Windows machine (iso-8859-1) and I regularly need to fetch them. I'd love to see how find and/or grep can do the same as convmv.
While modifying the definition of my PS1, I saw that "[" and "]" markers should be added to help bash to compute the right display lenght. Many exemples on the web do not use them or even mention them.I searched for a solution to add them automatically, like with sed, but I didn't find any example.Are they still needed and is there a recommandation not to use sed to define PS1?
I created a file holding all the md5 values of my files to find duplicates as follows: find /mnt -type f -print0 | xargs -0 md5sum >> ~/home.md5
I then tried to find duplicates and do ls -l on the result in such way: cat ~/home.md5 | awk '{print $1}' | sort | uniq -c | sort -nr | awk '{print $2}' | head -n 10 > ~/top10.md5
Now I attempted to do an ls -l on the files using the command: for i in `cat ~/top10.md5`;do grep $i ~/home.md5 | while read checksum path; do echo "`echo $(printf '%q' "${path}")`" | xargs ls -l; done; done
This works well on most files, however it does not work when filenames have special letters in them that gets escaped such letters with accent etc. These become for examle 303.
Are there any ways I can use the escaped 303 strings with path names, or any better way I can do this?
And what I'd like is to have the files renamed like this:
Code:
How could I code it so that it removes the numerical part of the filename (at the beginning), even with different patterns (like the 01 - artist vs the 01-artist)?
I've got a basic script, which parses data from a text file and performs actions based on that data. Here is my code:
Code: dsrc="/home/russellm/sites/" ddst="/home/russellm/othersites/" while read SiteID do if [[ ! -d "$ddst${SiteID:0:1}" ]] then mkdir "$ddst${SiteID:0:1}" fi mv "$dsrc${SiteID:0:1}/${SiteID%*}" "$ddst${SiteID:0:1}/" | tr -d ' ' done < sites.txt
The text file came from a windows system, and contains those return characters (). I 'could' just run the whole thing through tr and then run the script on the new data file, but I'm looking for a more elegant solution. As the code above shows, I'm trying to pipe the mv command though tr in order to remove the return character - but it's not working. I can't get this to work with sed either, so I know I'm doing something wrong. I also tried to remove it using ${SiteID%} - but that also failed. The characters don't show up in an echo, just when executing a command.
Output example (emphasis mine): Code: mv: cannot stat `/home/russellm/sites/B/B23467324 ': No such file or directory I'm tempted to just convert the file once and call it a day, but you know what it's like. To be honest, I'm starting to suspect that there are no return characters, and that I'm going about this wrong.
I'm trying to change the Xfce Terminal Emulator prompt from bash-4.1$ to something like what kconsole has. If i issue a /bin/bash -l in the terminal, then I get the prompt and the colors that I want, but I'd like this to automagically happen when I click the Terminal icon in the Xfce panel.This is for Slackware 13.37 (32bit) and Terminal 0.4.6
I changed the default SUSE prompt setting by modifying the shell variable PS1 to display the following information:
u : the username of the current user h : the hostname up to the first '.' w : the current working directory, with $HOME abbreviated with a tilde
I used export command to setup a new shell prompt:
export PS1="[u@h: w]$ " To add colors to the shell prompt and make a regular user prompt blue I used the following command syntax:export PS1="e[0;34m[u@h: w]$ e[m "
Just tried to install a minimal F13 from the first CD. Picked minimal as the choice and it still asked for CD #1 and #2. I'll have to doublecheck if that can be averted by manually unchecking everything. However, a bit more disturbing--though that's annoying enough--was the fact that I, on a VM at least, couldn't get to a bash prompt during the anaconda installation. Is that normal now? Can anyone confirm or correct that on an actual hardware install, vs. a VM?
One used to be able to, with F5, or maybe F1, IIRC, get to, during a Fedora installation, a shell prompt, the way the vast majority of distributions do. I'm wondering if this is just an oddity due to the VM and possibly Fkeys not working properly, or something else that they've taken away from from Anaconda.
Is running a command in the Alt+F2 prompt possible in a bash script?I need this for a launcher for gnome-shell.For it I have written a little script to check if the process gnome-shell is alive and act accordingly.The script works fine, I just don't know how to write "debugexit" to the Alt+F2 prompt, as that is the only decent way I have found to shut gnome-shell down and going back to gdm desktop smoothly.
I am getting more and more comfortable working with the shell, thus I would like to change its prompt color to my liking, as it will be easier for me to distinguish commands vs. outputs.
I've read a couple of instructions of how to change the .bashrc file and am familiar with what the codes in PS1 mean. Except, this file can be intimidating to newbie eyes.
Where exactly on the file is it that I need to make the change?
Here is what I am trying to do. I would like my prompt to like exactly like the prompt I use in Backtrack - which consist in two different colors, one for the host and another for the pwd. Here is what the Backtrack .bashrc file looks like:
# /etc/profile: This file contains system-wide defaults used by # all Bourne (and related) shells. # Set the values for some environment variables: export MINICOM="-c on" export MANPATH=/usr/local/man:/usr/man:/usr/X11R6/man:/usr/local/share/man:/usr/bin/man:/usr/share/man export HOSTNAME="`cat /etc/HOSTNAME`"
[Code]....
I also read that in order to have the same results when I log in as root, I will have to copy the modified .bashrc file into /root
I'm creating a bash script to do some tasks for me. I would like the script to be run at a set time of everyday. My first question is if it is possible that if one of the commands in the script requires sudo, is there a way to get around it with out making sudo not require a password. Such as, is there a way to include the password in the script? If that is the case, I can always just set the file as read only by sudo. I've been looking for a way to do this, with no success. if I have a command that wants input, how do I give it to the program. For example, if I want to make a zip file that is encrypted, the command would go as:
Code:
zip -r example * -e
now how would I get the script to insert my wanted password.
I am working on different versions of Ubuntu & I looking for a script that will prompt the user to enter the host name & user name that he wanted for that system at initial boot up.
