how to program in bash, an i have a problem, i am trying compare values in between 2 values (from another file), so far my solution is to make a nested for loop, but that causes it to compare every value. Here is a visulization of what i want
file.a 2,3,4,5 file.b 3 5
[code]...
i want the values 2, 3, 4, 5 from file.a to be compared inbetween values 3 5, 6 9,1 2, 4 7 from file.b (var1 is the value im comparing, var2 is the less value, var 3 is the greater value)
for i in $var1 do for k in $var2 do
[code]....
my problem with the above code is it compares EVERYINNG, not the values inbetween what i want (which is 3 5, 6 9 etc).
I am writing a script to get the multiples of 2 and 3, place them in an 2 arrays, and then show the common integers. So far everything works fine till the comparision. I don't know how to compare them. Here is the code:
I want to compare 2 name files, for instance. I got the package foo1.tgz and the foo2.tgz. and I want a script in bash that detects foo2 is newer than foo1 and delete foo1. Can it be done for managing collection of slackware packages.
I am trying to write a script which compares a log file with reference file. The log file has a table, the LHS of the table are constants strings and RHS of table values changes if there are any changes in configuration.code...
Here I am looking for a script which compares test.log file ( whose RHS data-types are known prior whether it is digit or string) with test.Ref which is reference file for test.log file. It will be really helpful for me if any of you give some idea about writing this script.
I have a (rather large) database of mp3 track information. I also have several directories of the actual mp3s. I'm trying to write a simple bash script that will check the contents of the directories against what's in the database, and upon finding a file that isn't in the database, do something.
Here's what I have so far:
Code:
The trouble I'm having (in the sample directory of "/mnt/music/B/Beatles, The/" the file "Beatles, The - Taxman.mp3" isn't in the database.) is getting it to actually trigger an error when an entry isn't in the database.
Once triggering on a non-entered file is working, any way to get it to traverse the entire /mnt/music hierarchy?
I create a bash script that writes another bash file. But in the generated bash file I want to write a bash command in the file and not executing it.Here's my bash file:
Code: #!/bin/bash cat > ~/generateGridmix2data.sh << END
I'm using Linux Mint 8 64bit with Google Chrome Unstable (same problem with beta).When a video is playing, the time elapsed and total time stay on the screen:Is there a way to make this disappear
then I cnf=`ifconfig` thus giving me the config of the NICs.after that I want to compare the $cnf to see if the value of it is listed in the file and if it is do things.There might also be something better to use then the 'ifconfig'but it worked so I just stuck to it First I just had one subnet but now it's starting to grow and I wanna make a list instead of having them all listed in the if-statement.
I am looking for a way to print the timestamp of a directory using find command. I can do that for a file, but for a directory, it is printing the contents of the directory as well. Lets say there is a directory called doc, and there are more than one occurrences of that directory.
find . -name "doc" -type d -exec ls -l {} ;
This is printing the contents of all the files under doc directory as well.
I have a list of locked accounts, called lockedusers, how can I with a bash script compare it to /etc/passwd on the server and print them out if they match?
I am trying to compare a list of patterns from one file and grep them against another file and print out only the unique patterns. Unfortunately these files are so large that they have yet to run to completion. Here's the command that I used:
Code: grep -L -f file_one.txt file_two.txt > output.output Here's some example data:
I am using makefile to complile all C Programming files. But certain files are not getting compiled and hence its object file is not getting generated. This is happening due to files haven't been modified for a long time. It seems that compiler knows that its object file is there hence no need to complie it actually it is not.
I am supposed to take some small files, and print them to a specific printer, such that the small files are concatenated into one file. The file name has to be included in the file that gets printed.
Should I be looking to concatenate the files into one file with the file names included, and then print them?
I have an internal hard drive and an external hard drive, both with about 350 GB of data. The data came from the same source, but over the last couple of years, different people have moved files around to different directories, and some files have been deleted. Now I want to merge all the files onto the internal hard drive. I estimate that 80% of the files on the external hard drive are the same, so I don't want to copy 290+ GB of data over when I already have it.
Therefore, I need a way to find just the files on the external hard drive that don't already exist on the internal one. In other words, I need to create two lists of file names irrespective of directories and compare them, selecting only the file names that exist in one list OR the other. I've Googled for solutions but can't find anything suitable. There are ways to create text files of the file names and compare them with diff, but they have to be in the same order, and since these files are in vastly different directories, that won't work.
I need to get names of all installed packages in 2 machines and save them in 2 text files, then I want to compare these 2 files to know the differences between 2 files and from that I could know the differences between 2 machines. Is it possible to do that and what program I could use?
I've created a bash file that calls another bash. And I would like to get the pid from the second file launched, to wait for the file to ends. The second bash file launches processes in background. How can I get the PID from the second bash file?
how to update a file that is already exist in bash. so far i haven found any. I'm using parameter as my first start for the existent, copy file to a different directory.
