I want to watch a number of processes in "D" status repeatedly with following command:Code:# watch -n 1 'top -b -n 1 | awk '{if ($8 == "D") {print; count++} } END {print count}''but it didn't work. I also tried with double quote. Can I use 'watch' command is this case?PS: I know 'while' and 'sleep' can do the same but it is dirty workaround.
View 2 RepliesI want to convert double quote to single quote in a text file. I tried escape characters however no success. Please find details as follows:
-sh-3.00$ sed 's/"/'/g test.txt
sed: -e expression #1, char 7: unterminated `s' command
-sh-3.00$ cat test.txt
"unix"
I want "unix" to be converted to 'unix'
I need to find each line in a file which does NOT begin with a double quote (") and append that line to the previous line. I have been successful doing this using the following command:
cat filname.csv | sed -e :a -e '$!Ns/
[^"]//;ta -e 'P;D' > newfilename.csv
My issue is the substitution. As you would expect after the line is appended to the previous line the first character is removed. I need it to not be removed. I tried:
cat filname.csv | sed -e :a -e '$!Ns/
[^"]/&/;ta -e 'P;D' > newfilename.csv
but it just hangs.
Goal:
Input:
"line 1"
line 2
Output with existing sed command is:
line 1ine2
I need it to be line1line2.
I need sed to be able to search a string that includes both single quotes (') and double quotes ("). can anyone help me out, there has to be a way to do this.
So far I have tried:
But none of these work and I cannot think of how else to escape the sed quote inside of brackets.
There is probably a very simple fix, but its wrecking my buzzI call the following on the command lineR CMD BATCH '--args Y_filename="one.txt" out="two.txt"' brew.RI want to call this from a bash script but replace one.txt with $1, and two.txt with $2 (ie the first two arguments from the command line)I have tried in vane"R CMD BATCH '--args Y_filename="$1" out="$2"' brew.R"
View 8 Replies View Relatedthe project I'm working on requires parsing a text file with fields separated by the | char and using perl to insert/update a mysql database. Some of the fields are simple numeric and others are text fields. In some of the text fields I run into a problem creating a proper insert statement for the perl api to mysql if I don't escape the single quote (') char with a backslash (). I can take each text file and do a manual subsitutiton, but I would prefer to use the script that prepares the text file to do it for me. I've tried sed (ex: sed s/'/\'/g ) and it runs cleanly, but does nothing to accomplish my goal. I suppose I could write a function to read the file character by character and write it out that way, but it seems a waste.
View 2 Replies View RelatedI am arthritic and I have considerable difficulty with a double click. I also have difficulty when using a mouse of moving the mouse as I select something (click the button) from whatever window I am working with and thereby selecting the wrong thing. To compensate for this difficulty, I use a Logitech trackball and program the center button to perform a double click with one stroke. I am currently struggling with Linux Mint 9 in my search for a Windows alternative. Is there any way to program my center button (scroll wheel) to perform a double click in this or any other Linux version? Alternatively, is there any way to program a keyboard key to perform a double mouse click with a single stroke? I do not want any multiple key combinations for this operation, I want something that works with a single click of one button.

when i click my mouse on something, it sometimes registers as two clicks. it doesn't happen all the time, but frequently enough to be annoying. for example, when i click a videos video to pause it, it often opens into fullscreen (which you normally click twice to do). also, in the url bar of chromium, i can't select the entire url by clicking. i now need to use ctrl+a. that's also because when i try to select the url, the highlight randomly disappears.
if i have multiple windows open, my click on the first "x" of the top-most window also closes the next window. i'm on linux mint 10. it's not really important, but it drives me crazy sometimes when my mouse doesn't work the way i want it to.
I am trying to ssh into my server from the command-line without including the username in the url. I do not want it to send any username, as it currently takes the active account and sends that as user.ex:
ssh server.com -> (doesn't send default username)
instead of [URL] I would want to input username directly into the server, just like it is done using putty on windows. he wants to be prompted for a username, rather than having to provide one when connecting - but I don't really see the utility in such a thing. - birryree Sep 8 at 17:41

Just a minor frustration, I have not found how to do this, double clicking serves what purpose? Am I going to change my mind between clicks?

Description of Problem:There is another thread that discussed this same problem that I'm having: However that thread is so old that the suggestions in it no longer work in Ubuntu 10.04 and for whatever reason I can not make a reply to that thread.As in the above thread, I've tried other input devices and rebooting the computer and using other USB ports, and my mouse still intermittently double left clicks randomly at times when I've only clicked the left mouse button once and at times and places when it should only produce a single click such as when selecting a drop down menu.
Has any one else had this problem, and does any one have any idea how to fix it or to trouble shoot this a bit more? Please let me know if there is any other information I can provide to further clarify or troubleshoot this issue.
About a week ago I installed some updates. What they were I don't remember. After I did that my mouse started acting up. Now about half the time when I single click it registers as a double click. Also when I click and drag to select text anywhere it'll randomly do another click screwing up that process.
So far I think the problem is when I press the left mouse button it registers the left click and then when I release, it randomly registers another left click.
The mouse itself works fine if I take it to another PC that's using windows.

I'm trying to create a user john with default password 'abcdef'. I used the following command.
useradd john -p abcdef
I can't login with the password. in /etc/shadow file I can see the password in clear text format. how I can create a user along with password.
I wish to allow a user to use sudo to run a single command (service app status) to determine if my application app is running, in my sudoers file i have: user ALL= /sbin/service app status I understand that there is a parameter called timestamp_timeout that will set the timeout for the 'user', but requires at least 1 entry of the root password.
I wish to allow the user to do "sudo service app status" and not have to enter the root password ever(maybe once is ok), but still make the user enter the root password for all other root activities. Is there a way to prevent the password entry for this command only and no others?
I am not sure If anybody has faced this issue, my keyboard is less responsive when pressing the double quote/single quote key, I have to press it twice for it to print the quote( and that too it prints some other data and not exactly a double-quotes). Initially I thought it was issue with my keyboard, but later I see that it is working fine in Windows XP. It looks some kind of setting issue. If you check the below two examples, example a) is the double quote printed in Ubuntu, it doesnt exactly looks like a double-quotes and b) is the one printed in Windows.
