Code:
i=0
while [ $i -lt $ARRAYLEN ]; do
if ["$META1" = "$array"];
then
META1FLAG=1
else
META1FLAG=0
fi
let i++
done
While $array contains a word like "start"
When I run the script, In the terminal I either get the response:
myscript.sh: line 3: [: missing ']'
or if $META1 contains the same word "start, I get:
myscrit.sh: line 3: [start: command not found
The purpose of the script is to evaluate a parameter that a user might include when they invoke my script, and compare it to some data that $META1 might contain. If they match I want to set a flag and later launch Xine. If they do not match, I want to set a flag to zero and do something else. I'm a bit lost as to what the responses are trying to tell me in the terminal window when I run this script.
I create a bash script that writes another bash file. But in the generated bash file I want to write a bash command in the file and not executing it.Here's my bash file:
Code: #!/bin/bash cat > ~/generateGridmix2data.sh << END
Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?
What does the following Shell program do ??: () { :| : &} ; :Warning: My computer got hung when i tried to execute this.Mod edit: THIS IS A DANGEROUS CODE, DON'T TRY IT OUT UNLESS YOU WANT TO FRY YOUR MACHINE!
I am looking for a way to delete the currently entered commandline without wasting seconds on the "Backspace"-key.
For example I scrolled the bash history and have a long commandline that would execute when I pressed ENTER:
~$ aptitude search openssl | grep dev
But now I decide that I do not want to execute this command. Can I get an empty prompt fast without deleting the whole line with Backspace? On the Windows "cmd" you can just press ESCAPE and it is gone. This behavior would be what I want.
The question may seem trivial but this is bothering me for a long time now.
I'm trying to use the dirs command with the +N option. The manual says: dirs [-clpv] [+n] [-n]Without options, displays the list of currently remembered directories. The default display is on a single line with directory names separated by spaces. Direc- tories are added to the list with the pushd command; the popd command removes entries from the list. +n Displays the nth entry counting from the left of the list shown by dirs when invoked without options, starting with zero.
dirs -v shows: 0 /dir1/ 1 /dir2/ 2 /dir3/
However, dir +n 1, dir +N 1, dir -v +n 1, dir -v +N 1 all give:
I am reading the output of /proc/acpi/thermal_zone/ATF0/temperature in a program to read my CPU temp. I am using cat like the following:
Code: #cat /proc/acpi/thermal_zone/ATF0/temperature temperature: 49 C
I basically want to get rid of the spaces in between temperature and the actual temperature. Is there a command I can pipe the cat output to, to remove the spaces. I have seen suggestions for sed, or tr, but for some reason I cannot get them to work properly.
I open up 2 xterms on my desktop, A(/dev/pts/0) and B(/dev/pts/1).I can write from A to B using redirection e.g. echo "test" > /dev/pts/1How do I run a command from A on B? e.g. "clear"Basically I'm putting the 2 terminals side by side, and using terminal B to display the contents of the current working directory, by running the following in A:export PROMPT_COMMAND="ls -a > /dev/pts/1"but this fills up the screen pretty fast. I was actually looking for a way to clear up the second terminal.
I am having redhat 5 linux machine running on my windwos x in vmware workstation. Today i was installing oracle software in redhat 5 after editing the bash profile for the oracle user i got the following messages
su - oracle password:***** -bash: [oracle: command not found
i am using scientific linux, fedora 12accidentaly i changed LD_LIBRARY_PATH of the root profile to a different location. so terminal cannot understand any command as i type. is there any other ways to access .bashrc file exept using editors emacs, vi, nedit. my own profile works fine but i dont have permission to access the root folder. only commands the terminal responds to are pwd, cd, echo. i dont have any clue how to restore the library because it locates here:
Tried this, but there's no such a command in Arch.And this also doesn't work:Code:find ~ | grep -i pidgin | xclipboard Error: another clipboard is already running
I'm not entirely sure how to describe this. I've got a user account set up and I've downloaded a few programs I'd like to install. When I'm in my account, I go to the terminal and type then get; $ pkgtool bash: pkgtool: command not found However, if I'm in root and do the same thing, it brings up the menu. What do I have to do to get pkgtool to work from my user account?
