I'm new to bash scripting and I've searched around the forums and Internet for this but haven't had any luck. I've found similar things but not what I need. What I need to do is write a simple script that uses what the user inputs to locate and display where a file is. I would prefer to use locate instead of find since I know that the person I am writing this for has locate on her machine (my mom, who is just beginning with Linux).I'm writing the script to make things easier for her while she learns In this particular part of the script I would like to be able to have the script prompt to enter the file she is searching for, read the her input and then display for her where the file is. I realize it would in most cases be much simpler just to teach her how to use locate, but she is very impatient and this is just a part of the script I will be writing, but I can't figure out how to do this.

At the moment I got my md5sum checking working which I write to a text file and see below.
If the md5sum works it will write the output to check2.md5 test.txt: OK
If the md5sum fails it will write test.txt: FAILED
How do I write if statement to check the output whether or not the md5sum failed or not ?

I have a script which checks on my jobs that run on some cluster.The script, "script.sh", takes as an input the job-id for the job to be checked. Sometimes I have 100s of jobs and I want to check them all (for successful completion.) I could put these job-ids into a text file, "job-id.txt", each id in its own line.For each job-id, the script would ask me few questions (with a yes or no answers) to see if I want to do some other checks for each job-id.I want to know how may I direct my job-ids from this text file into the script one job-id at a time.
View 14 Replies View RelatedIs there a way to process individual characters one-by-one from a text file in Bash, or is that hoping for a little too much from this lovable old clunker?

I have to read first paragraph of variables and do some processing and then move on until the end of file. Variable names are same in whole file but for each paragraph the value is different. I can't think of a logic to attain this task. How can I do it? It should be a simple bash script, but I am not able to work out.
What i want to do is pretty simple.I want to uncomment every line that begins with "deb" (except for deb cdrom) in /etc/apt/sources.list.I know how to do this through system > administration > software sources.I know I can gksu gedit /etc/apt/sources.list.I'd rather not do it that way.I'd rather have a script do it. It's less work, less typing, less clicking, and would work the same on every ubuntu version.
View 8 Replies View Relatedi am on processing text tasks And i found that if you assign a text to a variable is chomp'ed automatically the newline

bash 3.1.17(2) I'm trying do write a shell script which must operate on each line of an ASCII text file.

View 6 Replies View RelatedI want to be able to check the contents of a text file for a specific string and remove it from the file from the command prompt.

I already have the search part sorted just need to be able to remove the string I don't want from the multiple files.

I want to delete all files within a specific folder without actually deleting the folder, what is a good bash command for this?. I found this one but encountered some errors even though I am executing it within the specific folder:
useratdebian:/home/user/folder# find . -type f -exec rm -rf {} ;
[1] 5052
useratdebian:/home/user/folder# find: missing argument to `-exec'
[1]+ Exit 1 find . -type f -exec rm -rf
The command as it appears is:
find . -type f -exec rm -rf {} ;
how to delete only the files contained within the folder called "folder" for example?
I'm trying to call a specific variable based on a user selection. For example:
Code: Select a file:
[1] foo.tar
[2] bar.tar
Enter a selection: I have already coded each possible selection to have its own variable. If the user selects 2 I need to select $SELECTED_TAR2, or if they select 1 I need to select $SELECTED_TAR1 and then do something like this behind the scenes:
Code: cp /home/user/$SELECTED_TAR2 /home/user/backup/$SELECTED_TAR2
I was thinking something like this:
Code: echo "Enter a selection: "
read -e SELECTED_NUMBER
cp /home/user/$SELECTED_TAR$SELECTED_NUMBER /home/user/backup

I look after a server which accepts automatic overnight PASV FTP uploads from remote clients. When the uploads are complete, my Bash script copies the files to another location. The problem is, my script needs to be a bit smarter when it comes to detecting active FTP sessions.
I was using:
Code:
netstat -n | grep ":21 " | grep ESTABLISHED
to test if there were active sessions, but came unstuck when a local user left an unrelated FTP session active. The result - my script hung around all night thinking there was an active upload from a remote client. My server is behind a firewall, so remote clients all show an internal (NAT) address,so I can't differentiate by source IP address.I can't install LSOF or FUSER for security reasons. Is there a way I can test for active FTP sessions from specific users? I am running Red Hat Enterprise Linux Server release 5.2 (Tikanga).
I need to insert 3-4 lines of text to the beginning of a text file. The file is a largish MYSQL dump, the result of a backup shell script. This shell script should insert the required text.I've wrestled with sed, but lost.
View 2 Replies View RelatedI 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.

I want to display the contents of a particular log file (simple text file, I mean in Linux). But there is a problem: The contents need to be organized in a fixed format. Have a look at this log file:
sampleLog.txt

So, while displaying the contents of above file on a web page, I want to format the field names found in the log file: User Name:, Reported Problems Description:, and Remarks:. These fields may contain a variable length of text and no specific line number is assumed for them to appear on.
The desired output should look like this:
User Name: XYZ
Reported Problems Description: Blah! Blah! Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah!
