the script below prints the pwd of where I want to be. after the fi it puts me back at the original dir. just writing these scripts to understand what's going on.
#! /bin/bash
if
[ -d mydir ]
then
cd mydir/ && pwd
fi
We are building our C++ project in Kdevelop IDE. Every time we run "Run Configure" from the "Build" menu, a file named "libtool" gets automatically generated. This file contains a statement as "ECHO="echo"".f we run "Automake", without modifying the "libtool" the system hangs and theputer needs to be restarted.Therefore every time we run "Run Configure" we need to include the line "echo="echo"" below the statement "ECHO="echo"" manually.I think a script can be written which does the above on its own.I am not a shell script programmer, I know the good tutorials for shell scripts are available on the net, but learning scripting only for this task would be time-consuming and painful.

I want to have an if statement that does multiple things:
Code:
if [....] ; then
1=...
2=...
[code]....
I'm a bit stuck with IF statement. There is the code:
#!/bin/bash
# Variables
VAR1=test
VAR2="echo $VAR1"
# Case 1
echo Case 1
if [ test == test ]; then
echo "equal"
else
echo "not equal"
fi;
echo ""
# Case 2
echo Case 2
if [ "VAR1" == test ]; then
echo "equal"
else
echo "not equal"
fi;
echo ""
# Case 3
echo Case 3
if [ "VAR2" == test ]; then
echo "equal"
else
echo "not equal"
fi;
echo ""
When executed, why case "2" and "3" differs from case "1"? Where am I wrong and how to solve this trouble? (my aim is to get "equal" from all cases).
I want to have the System Bell ring when a process is over say a download. First I created a file named 'beep' that plays the System Bell. Because the System Bell rings by hitting cntrl-G the 'beep' file looks like this.
Code:
echo ^G
I then give the file owner execute permission. I know that this command would serve my purpose.
Code:
[URL]
However I want to sharpen my Bash programming skills. I wanted to write the Bash script along the following logic and with the fewest lines possible. Not really a script, I want to insert this short script via command line instead of a file. Let's say the download has commenced and the PID = 16666.
Code:
until ps -p 16666
do
/root/beep
done
Now obviously 'ps -p 16666' will already evaluate to true. My question is, is there a way to maybe enclose 'ps -p 16666' and prepend some operator that inverts the condition to where until 'ps -p 16666' evaluates to false then run /root/beep?
I need to to write a bash script using an If...Then...Else statement that will accept a day of the week from the command line what do I do or where do I go.
View 2 Replies View RelatedOn Ubuntu 9.10 I installed Python 3.1.1 successfully with Synaptic Package Manager. However the Python interpreter cannot find my scripts, currently in /home/dave/pycode. This appends _temporarily_ but python remains clueless about location of my scripts. Searched Internet and some speak of .rc or .bashrc or .profile..files. Found some of these and opened with Komodo : they are Linux script files and I am clueless as to how to modify.Currently I can import my scripts only if I change to the /pycode dir before running.Lutz's Python book says to change PATH file - Ha .Sobell's "A practical Guide to Ubuntu Linux" is no help.

Im a bit stuck with a simple script that im practicing with... im trying to get my head around some simple scripting. Basically i want to write a script that will work as below: It will ask the user to enter their userid. If its correct it will say 'Correct' If its the wrong id (But the ID exists in /etc/passwd) then it will say 'incorrect' If its not a valid userid it will say 'doesnt exist'. What i have so far is:
[Code]...
# If the user enters their own userid they will get a comment saying 'correct' $LOGNAME) echo "Correct";;
# If they enter another users ID (That exists in the /etc/passwd), then they get a message to say 'incorrect userid used'. Im not sure what i need to do here to get it to check the /etc/passwd to see if the input exists in there.... im guessing some kind of simple 'if' statement to say ---- "if 'input' exists in /etc/passwd then echo "incorrect userid used"
# If its entered incorrectly and not a valid ID then they will get this comment. Again, im guessing this part would be similar to te above option..... *) echo "not a valid ID";;
Ive managed to work out how the basic Case staements work, but to add a conditional statement based on the input, i just cant figure out. I have tried looking on google, and found some help but it doesnt really explain how i check the input against the /etc/passwd.
I am trying to write a script that takes an input file ($FileName) and an intermediate file ($FileName.info) and removes lines from $FileName if the value in $2 of $FileName.info is <75.
I can't figure out how to feed only one line of the .info file to the if statement at a time so that it will perceive it as an integer instead of a list.
The error I am getting now is ./script.sh: line 6: [: : integer expression expected
Sample input $FileName
