Red Hat / Fedora :: Bash - Echo Multiple Numeric Values On One Line
Aug 9, 2009I'm trying to get multiple numeric valued version information into a variable, all on the same line. I want for example $VERSION=3.1.0.01.002. I'm trying to pull seperate values from the file named version.properties, wherein the file contains;
patch.rel.num=0
sqa.num=01
major.rel.num=3
build.num=002
minor.rel.num=1
So I have the following script:
#!/bin/bash
BUILDVERFILE="version.properties"
PATCH=`grep "patch.rel.num" ${BUILDVERFILE} | awk {'print $1'}`
SQA=`grep "sqa.num" ${BUILDVERFILE} | awk {'print $1'}`
MAJOR=`grep "major.rel.num" ${BUILDVERFILE} | awk {'print $1'}`
BUILD=`grep "build.num" ${BUILDVERFILE} | awk {'print $1'}`
MINOR=`grep "minor.rel.num" ${BUILDVERFILE} | awk {'print $1'}`
P=`echo $PATCH | tr -d .=[:alpha:]`
S=`echo $SQA | tr -d .=[:alpha:]`
MA=`echo $MAJOR | tr -d .=[:alpha:]`
B=`echo $BUILD | tr -d .=[:alpha:]`
MI=`echo $MINOR | tr -d .=[:alpha:]`
VERSION=$MA.$MI.$P.$S.$B
echo $VERSION #
I end up with the value of .002 ?? Seems like it's only getting the last portion because if I run the script thru "bash -x" I get:
...
+ VERSION=$'3
.1
.0
.01
.002
'
+ echo $'3
.1
.0
.01
.002
'
.002
General :: How To Echo Redirected Stdin
Sep 26, 2010I execute an application from a script file and redirect stdin to it from here-doc like this:
my_cli << HERE_DOC
enable
configure
10
exit
exit
HERE_DOC
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?

Feb 25, 2010I'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.
General :: Use The -ne Flag For Echo In A Shell Script?
Jun 21, 2011I'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.
General :: Prevent ^C Echo When Ctrl-C Is Pressed?
Jan 10, 2011I 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.

General :: Turning Off Echo In Shell Script
Feb 27, 2011Would 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.

Sep 16, 2010We'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:
Code:

View 8 Replies View RelatedGeneral :: Command Not Found For All But PWD And Echo - Path Empty
Mar 1, 2011I 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.

General :: Ext3 Filesystem Mounted In Ubuntu 9.10 (Echo Error)
Apr 19, 2010I 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.
