Programming :: Pseudo Virtual Files In Shell Script?

Jan 30, 2010

Perl has the concept of pseudo virtual files where data can be appended to the end of the script, & Perl will treat it as a legitimate source of data:

Code:
$ cat pseudo_file.pl
#!/usr/bin/env perl
use strict;
while (<DATA>) {
print; }

__DATA__
1
2
3
$ perl pseudo_file.pl
1
2
3
$ _

I would really like to be able to do something similar in a Bourne shell script where I don't have to manage a collateral text file which is prone to getting lost. Does anyone know if there is a similar construct in shell programming? I would have thought this feature was a remnant that Perl inherited from its shell programming roots, but searching on the Web has revealed nothing of consequence.

Programming :: Updating XML Files Using A Shell Script?

Apr 1, 2011

I continue to work on automating the update and deployment of a vendors WAR files, and have bumped into my next challenge... The vendor provides web.xml files have entries that look like this

Code:

<context-param>
<param-name>siteminder.enabled</param-name>
<param-value>false</param-value>
</context-param>

I need to search the file for a param-name and replace the param-value below it with the correct value. I expect sed or awk is the trick on this, but I am not sure how to have it search for one line, and have it update the line below it.

Programming :: Compare Two Files Using Perl Or Shell Scripting?

Mar 8, 2010

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
ih509rs12345467244750"G,G"
ih499rs6049687244911"C,C"
ih508- 7244977"A,A"

Programming :: Shell Script On Placing Files Across Mount Points ?

I have a database with x number of files (192 at the moment, but will vary from time to time). I am going to copy these files to another location on the same server thorugh shell script. Problem with total size of 192 files is approx 900 GB (again this will vary from time to time).

After calculating, it should prepare another flat file with following details:

Programming :: Shell Script To Automatically Delete Files With The Same Name As The Parent Directory?

Mar 18, 2010

I am facing a problem in Windows due to a virus called Newfolder.exe which creats files with the same name as it's parent directory and an extension .exe and this happens for every directory in the entire hierarchy in the infected pen drive. The antivirus detects them, but is sucking slow. So I thought this is a good opportunity to use the concepts of the all mighty shell script to remove those as they follow the same pattern. Say my complete path is

Code:

/home/pkd/fol1/

The virus would have created an file with complete paths

Quote:

/home/pkd/fol1.exe

If fol1 has two more directories fol11 and fol12 Then there would be two more .exe(virus created) in the following path

Quote:

/home/pkd/fol11/fol11.exe
/home/pkd/fol12/fol12.exe

Programming :: Create/delete Temp/backup Files Through A Shell Script?

Dec 31, 2008

I have a shell script that need to create some files:

1) backup files of user passed in file ( that will be written by this shell ).

2) temp files that the shell will create and later delete/remove.

This shell script will be used from my local dir ( I am not a super or a sysadmin ). Users of this shell will call this script to run on their local files in their respective directories. When my script runs, it errors with the following:

cp: cannot create regular file `./listfile.txt.backup': Permission denied
/home/myUser/tools/myShellScript: line 12: listfile.txt: Permission denied

for the temp I was able to avoid this error by creating the temp file in the /tmp directory. All I want is for this shell script to run, create/modify/backup files in user's local dirs.

The user dir has the following permission:

drwxr-xr-x testDir

the file that needs to be backed-up has:

-rw-r--r-- listfile.txt.

Programming :: Shell Script To Copy Newly Changed Files With Rsync?

Apr 20, 2010

I've got quite a decent rsync script setup, however I'd like to invoke it whenever there's change to a file. My initial idea was to use find, however this has two major flaws - the first being my particular unix veriant cant understand -print0 which means this doesn't work, the second is that I'm not 100% sure how to put variables into quotation marks so ls can understand the target:

Code:

for i in `find /shares/ -mtime -1 -print`; do ls -ltr $i;done

Programming :: Bash-shell-like Less Functionality In The Python Shell?

I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.

Ubuntu :: Shell Command For Finding All Packages That Provide A Certain Virtual Package?

Jul 29, 2010

I want to get a list of all packages that provide a certain virtual package. A way of doing this would be to write a shell script that parses all output of Code: apt-cache search -f .* And spits out all packages that have the virtual package in the provides section. The problem with this approach is that it takes an awful long amount of time to execute. I guess that there should be a simple command that does this in an efficient manner, but which I wasn't able to find.

General :: Shell Script To Shutdown Virtual Machines / Copy And Than Start VM?

**copy or rsync to /home/gareth/vmware-backup/ dir**

[code]....

1. Just to confirm, I need to place the above in a file with #!/bin/bash at the top and make it executable.

2. How do I know when the VMs have safely shut down so I can start the copy? I guess I can either a. wait a specified amount of time b. run some sort of if statement to confirm they are off.

3. How do I use Rsync or cp to copy to the backup folder?

4. How will I know the copy is complete so that I can start the VMs again?
