View 1 Replies View RelatedI have 2 files to compare and then print out information that match a certain pattern. I know basic scripting and was heading down the path of merging the 2 files together but this is the wrong approach. Would really appreciate a script that can do what is required:

View 1 Replies View RelatedWhat is the best and simplest way to compare two directory structures without actually comparing the data in files. This works fine:
diff -qr dir1 dir2
But it's really slow because it's comparing files too. Is there a switch for diff or another simple cli tool to do this?
what command is to be used to call strings from other files to the script and then comparing strings from two different files in the script to check if strings are matched then return the result to another script.
View 1 Replies View RelatedI have some data ( seperated by semicolon ) with close to 240 rows in a text file temp1. temp2.txt stores 204 rows of data ( seperated by semicolon ). I want to : Sort the data in both files by field1.i.e first data field in every row. compare the data in both files and print out the rows that are not equal in seperate files. I was trying to do this with excel using vlookup, without a great deal of success. hence, i'm exploring the shell script option.

Let's say I have file A, and using 'ln -s A B', I have B. When I open, edit and save B, now B is not symlink anymore. It's just a new copy of A. Is this expected behavior? I use Mac OS X, and I wonder it's common in UNIX. In this case, is there any way to keep B as a (soft link) to A? Or, make B as the hard link would be the only way to solve this issue? What's the advantage of using soft link than hard link? The editor that I use is 'TextMate' on Mac.
View 1 Replies View RelatedI am using the diff command with the -r option, to compare a large number of files and files in subdirectories. My main interest is to find out which files have been changed, and not what the actual changes are, and since a lot of files has been changed, it would be a lot easier to view the file names only. Is there and option for diff that might do this, or does there exist a similar tool/command that could do the job?

View 5 Replies View RelatedLets say I log in to bash, open a file in vi, then using alt-f2 I open a new terminal. After logging in I navigate to a second file and open that in vi. How can I CnP between these two files?
I found this from [URL]. I'm not familiar with this command shift-8-y-y. I follow the vimtutor and use virtual mode. I tried this sequence and was unsuccessful.
And, I read this about registers. I found a mention of using double_quote-p to 'put' or paste the register, but this does not work in a different file. The second file reported the register empty.
Alternatively, I read in the VIM docs, it is possible to open multiple files under split screens. This may be a course to a solution. The need I often encounter has me navigating in a different bash window to find a file, then wishing to copy between the two. Whereas, I imagine, a split VIM window useful for files in the same directory.
I have two files (not sorted) and need to compare line by line (i.e. first line of file1 to be compared to all the lines of file2 and so as for the rest of file1). Output will be an array of length of file2. Any suggestion in BASH other than a grep inside two read line loops ( which is time consuming for files ~1000s of lines).

View 2 Replies View RelatedI have to write a script that accepts two directory names (JIIT, JUIT) as positional parameters and checks which files are identical in both directories and files having same contents are also considered as identical in same directory. I tried using diff:

echo "Enter the directories:"
read d1
read d2
cd $d1
if diff file1.sh file2.sh > /dev/null
then echo same 1,2

I want to compare the following two tab-delimited .txt files (both were subsets of the original files) by comparing Columns 3 and 4 simultaneously. It is easy to compare C3 because both C3s are just numbers. But how to compare C4s?Basically, in File1, "G,G" = G in File2, "C,C" = C in File2, "A,A" = A in File2, "T,T"= T in File2.In File2, A/T in Column4 just equals "A,T" or "T,A" in Column4 of File1. C/T in Column4 just equals "C,T" or "T,C" in Column4 of File1, and etc.
File1:
C1C2 C3C4

I need to create a script that will compare the differences between two folders and then to copy only the updated and new files only to another directory. I know I need to use rsync here, I can write scripts so really it not how to create a script it is how do I accomplish the transfer of only new or changes files between two folders to a new file. Do I need to link these two folders first and then use the "--compare-dest" switch.
