General :: Write Expdp Output In A Text File Using A Shell Script ?
Feb 7, 2011
I want to write expdp output in a text file using a shell script
If i write like below:
It will write whatever is there in log file to text file
But, sometimes export fails with out start taking export (without generating log file) because of job already exists error. such times, we dont know about that error until we check manually... so i wrote like below:
But still it is not writing anything in to text file using above stmt...
I want to write a shell script which will simultaneously collect OS user information and write in an individual text files.Can anyone tell me the syntax of the script.N.B. The user name will be mentioned in an array within the shell script.
im trying to output a list of running processes via a shell script. At the moment i got this which outputs the processes to a text file called out.
echo $(ps aux) >>out
The problem is though, the processes are all just one big block of text which makes it hard to read. Does anyone know how to sort the output to a text file so that it prints to the text file at 1 process per line? I know its probably simple but im very new to linux.
it compares two files using md5... if they are same , a corresponding character is output to a text file .. but the problem is it gets appended by default.. is there any way to output in a normal way because the text is a message and it should be of proper format here is my script
Code:
#!/bin/bash g=`tail -1 new.txt|head -n 1` array=( a b c d e f g h i j k l m n o p q r s t u v w x y z ) for((i=1 ; i <$g+1 ; i++))
[code]....
the message is supposed to be hello , i need to get rid of the endlines somehow..
I've been trying out qemu to play around with some VMs. It's working well but I keep wanting to be able to view the text (linux boot process) that quickly scrolls by in the qemu window on startup of my linux virtual machine. Is there any way to retrieve this via qemu?
I want to write a bash script to parse a text file with the following lines and set variables for each line so that I can use them in the rest of the script.
Timestamp=123456789 Company=ABC Company Server=Server Recipient=Joe Smith Email=joe@abc.com
simplest way to read each line one at a time for everything before the =, set that to a variable name with the value equal to everything after the =
I'm just starting out with shell-scripting, but having a problem with making new text files with the touch or cat > commands.
What I've been doing is touch testfile1.txt
Also, I've tried cat > testfile1.txt (text)
Console reports "bash: text1.txt: No such file or directory. Consfusingly, it works fine in the home-directory. But if I move the file to where I want it, I can no longer view, edit, etc. it.
I'm having a slight dilemma on reading data from a text file and outputting it into a table then displaying it. Basically I'm writing a shell script that takes information from text files then outputs the data into a table with 4 headings.he extracting of the data is fine, but creating a table i'm having problems with. I think it is possible to do it using the awk function, but so far i'm having a lot of difficulties.
Am having issues getting the output from a script to be logged in a file. I need the script to output both the stderr and stdout to the same text file.
I have two linux servers, they are backup together.
1. Server 1 have 3 files with name: file1, file2, file3 in the path: /etc/sysconfig/network-script/.
2. Server 2 have 3 files with name and path are the same as server 1.
- How to make a script to copy 3 files at server1 to overwrite on server2. But before overwrite, this script will check and compare the last modified date of these 3 files(on server1 and server2). if the modified date of file1, file2 or file3 on server1 is newer than 3 files on server2 then overwrite process will do, if not, will do nothing.
- see my script as below: it works find now but just overwrite. not check last modified date.
I am trying to write a script to access sqlplus and use the output to replace the result in another file. But I am having some issues with it (This script is just a test script and I am just trying to print the updated value.
I have a text file that contains a single word and I want to write a bash script that will read the word from the text file... The following is my incorrect attempt, as it assigns the name of the textfile to the variable as opposed to the word stored within the textfile:(assume I have a text file value.txt that has its contents a single word, say wordone)
Code: #!/bin/sh for f in value.txt do echo $f done
so the output of the above script is value.txt, however I want it to be wordone.to summarise: how do I assign the value of the word contained within a textfile to a variable?
Actually i m new to scripting in Linux, we have RedHat Server Edition 4 in which different software licences are installed and software itself installed at client side. the usage of the software is recorded daily in a text file which is of format
I want to write a script that checks that for any OUT & IN, if utility, user and Client PC Name are same then subtract OUT Time from IN Time. This has to be done for each & every user and utility.Is there any GUI programming possible in Linux.
I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.
Just using shell scripting, how can I insert text into the middle of a file name. The file has a predictable pattern, let's say 3 letters and 3 numbers and I want to insert text in the middle of those 2 patterns. Say ABC123 is the file name. As a result, the file name should be ABC.blah.123
I'm writing output of top command to a file However since top does not provide time I would like to append the 'date' command and then write all this to a file.
I have a number of text files throughout my /home/pjs/Documents directory tree that have execute permissions set. Almost all of my file names have spaces in them. I am trying to write a shell script that will look at each file in my Documents directory, find the ones that have execute permissions set, and run the command chmod 644. Of course, I don't want the command run on the directories.
The following script *doesn't work*, but might serve to illustrate what I am trying to do:
#!/bin/bash for x in "$(ls -R)" do if [ -f "$x" ] && [ -x $x ]; then chmod 644 "$x" fi done
I want each file and directory name to be placed, one by one, in the variable $x, and then tested with the "if" conditionals.
The first problem seems to be that, although the command "ls -R" does produce a complete list of the files and directories I need, they are not placed, one by one, in the variable x like I want them to be.
Also, I think I should use the shift command so that the option -R doesn't get included as one of the values of the variable $x, but I can't figure out where to put it.
-Qjackctl has a config file which is modified each time QjackCtl is shut down. This means that whatever preset is in use when QjackCtl closes is written into the QjackCtl config file as the DEFAULT PRESET, for the next time QjackCtl starts (or at least this is how I understand it).
-I want to edit a specific line in the QjackCtl.config file, which specifies the DEFAULT PRESET. Obviously its easy to do manually, but I want to do it using a shell script which runs automatically on StartUp so that QjackCtl starts every time with the same DEFAULT PRESET, NOT the last one used.
-Unfortunately Im not at my Linux system right now (which is KXStudio/Kubuntu), but I believe the QjackCtl.config line looks something like this: DEF_PRESET=alsa (where alsa is the name of the preset)
PRESET1=alsa PRESET2=firewire
I want a shell script which changes the line DEF_PRESET=alsa to DEF_PRESET=alsa, even when it may currently exist as DEF_PRESET=firewire due to occasions when firewire was the active preset when Qjackctl was last closed. I notice that the application in KDE that enables the user to set which applications open automatically on StartUp also allows the user to select shell scripts.
Ive done some research, as a beginner, and Im led to believe I might need to use AWK and/or CHMOD. I could have a go at writing a shell script but Im always wary about experimenting with StartUp scripts/operations because obviously if I get it wrong and make my system unusable, then because its going to run first thing on each boot, Id have great difficulty disabling it.
I am a novice to the shell script. In my system from db server the log files are enerating with the name log1.txt,log2.txt..... It is capable of keeping 10 files at a time in dir called /db/sis/log1.txt. I want to copy the log1.txt to another directory when ever it generating by attaching the time stamp to it for the back-up purpose. this files will be there for a period of 24 hours. after that the back-up dir should be cleared and it start copying again the fresh file from the same dir.
