Programming :: Pass A Path As A String To A Variable?
Apr 17, 2009
I'm trying to pass a path as a string to an array, but its evaluating it as a command instead. I want to take the literal string "/mnt/accounts/user/temp/*.jpg" and assign it to an array{1}, but when i echo the array variable, it displays it as
pic1.jpg
pic2.jpg
pic3.jpg
[code]....
I just want it to be the actual text "/mnt/accounts/user/temp/*.jpg" which i will be combining with other text to create a longer path elsewhere in the code.
my script has a variable which comes in the form +00.00 +0.00 -00.00 or -0.00 (the numbers can be any in that form) for any that have a + symbol I need to remove the +, but if it has a - symbol it needs to stay.
i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't
I need to pass variable from sc1.sh to sc2.sh and update the value of the passed variable in sc2.sh and then return the updated value of the variable from sc2.sh to sc1.sh.
I have some messy code that I wrote a while back and I am trying to organize it. The program opens xpaint and uses xwit and xte to draw packman and so on. I want to split it all up I am going to add more to it. Basically like i would want drawing packman in one function i guess you could call it and then coloring him or the background in another
#xwit -id $paintersMom -focus -raise #sleep 1 #xwit -id $paintersMom -warp 30 390 #// fill in command on tool bar #sleep 1 #xte 'mouseclick 1' #sleep 1 #xwit -id $canvasWin -warp 221 40 #// color selection #sleep 1 #xte 'mouseclick 1' #sleep 1 #xwit -id $canvasWin -warp "$(($X-150))" "$Y" #//location on pac man #sleep 1 #xte 'mouseclick 1' #sleep 1
#xwit -id $canvasWin -warp 62 44 #// selecting color black #sleep 1 #xte 'mouseclick 1' #sleep 1 #xwit -root -warp 62 120 #// selecting back to canvas #sleep 1 #xte 'mouseclick 1' #// color canvas black #sleep 1 #xwit -id $paintersMom -focus -raise #xwit -id $paintersMom -warp 27 108 #//click back to pencil #sleep 1 #xte 'mouseclick 1' #sleep 1 </code>
Here for example $paintersmom is would be in the drawing of pacman but I would also want to use it when I colored him in.. but I would want both processes in a different shell script.
I'm trying to create a program that would locate the oldest file of a certain type on a server. Here's the commands:
OLDEST_PATH=`find -L / -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1` OLDEST_FILE=`find -L $OLDEST_PATH | grep .mp3 | sort -f | head -1` ls -al $OLDEST_FILE
I'm writing this all in expect but I'm having problems. The main problem I have is whenever I try to run the first command, I can't seem to isolate the result of the OLDEST_PATH so that the 2nd command will work. There always seems to be a newline in the variable and the result is only "find -L" command running and it bypasses the variable. If I can just figure out how to get the 1st and 2nd command to work, then I can figure out the 3rd. Here's some code:
I know there is a better way to write this. I've tried multiple ways and this just happens to be the last way I've tried it. If you try running this, you'll notice that there is still carriage returns after the result of OLDEST_PATH and it prevents the 2nd "find" command from working properly.
I'm trying to write a python script that will use the current user's name when interacting. Ex: when started, it should say "hello daweefolk" when I am logged in. I've tried Code: username=os.system("echo $USER") but the variable remains empty. What is the correct code?
I'm new to UNIX scripting; I�m stuck with the following I have an Oracle SQL script that takes three parameters
1- File Name 2- File Path 3- File creation date
Under UNIX I have a folder where files will be placed frequently and I need to upload those files to Oracle, what I need is a UNIX script that can do the following
Loop through Directory "/home/applmgr/snktmp" Picks only files Pass the file name to parameter &1
[code]....
Is the above possible? I already knows how to call the Oracle Script from UNIX Im only stuck on writing the UNIX part where it List the files attribute(name,path,date) and store them to parameters ,Looping until the last file in the directory If the above is not possible,then how can I create the below from the command line
I have a program that loops over each word in a sentence. I need to append a constant to the beginning and end of each word. It works up until the last word on the line.
I want to append a variable string to the end of a specific line. not like append the same string to each line. like in my file i have 4 columns, i want to add a string in 5th column in some fixed row.
I think read A1 A2 makes A1, A2 string variables. Then, when A2 gets the value 01, '01' should be a string. But for some reason bash takes it as numeric. I know there are no types in bash.
having bit of a trouble with path expansion of strings that contain some whitespace and wildcards First my script sources a configuration file that contains array assignments
Code:
... BACKUP_TARGET_FILES[2]=/boot/config-* # no problems BACKUP_TARGET_FILES[3]="/root/random dir with space/file*" # this is the problem ...
then later in the script I want to expand BACKUP_TARGET_FILES elements as below
this code seems to work but I'm not quite satisfied with it. I'd like to get rid those IFS changes, but haven't found out a solution as of yet. Problem with default IFS seems to be that with it neither $pattern or "$pattern" work; it either interprets pattern as multiple words (because of spaces) and so expands to wrong paths or it ignores * because it's within quotes.
I want to replace a string of directory path in a string to empty:
Code:
But this doesnt seem to give me the desired thing:
Code:
This gives the desired outcome, but its specific, i need a variable in the sed not a string. And if I replace STRING="/mnt/sda1/record/$dd/" then I cant use it for something else, cause its has all the weird backslashes now.
Experimenting with shell variables, accidentally deleted the path variable how could I return to the original path value. What kinds of problems will I have if I don't have a path variable.
how to add a path to PATH variable permanently so that it remains persisent even after closing shell and rebooting the system when i added a path, to variable it remained there as long as i didn't closed the shell. but when i reopened it ,changed were undone.
I am trying to figure out how i can add the path /usr/sbin/ into the $PATH variable. I want this to be used from the normal account. I am bored settinh this manualy each time my computer starts.
I am trying to pass a variable to smbclient (OS X), but the variable is recognized only as its strict text.
Is there anything syntactically I have to do pass a variable created in the shell (bash) to smbclient (or perhaps any other interactive app)? I've seen references to variables as $[variable] or ${variable} but I've not been able to figure out what works.
