To test whether Samba is installed or not…
type following command…
testparm /etc/samba/smb.conf
Testparm will parse your configuration file and report any unknown parameters or incorrect syntax. It also performs a check for common misconfigurations and will issue a warning if one is found.
chidamla replied the topic: Re:How to access windows share folder from linux
Samba is one method.
Another method is to execute an ftp service in any Windows server and configure the Windows share drive as the home folder in the ftp service. Connect Linux server to the ftp service to transfer files. This set-up is worth it when there needs to be frequent transfer of files.
For one time transfers use, winscp tools.

Nested for loop in Linux Shell Script
scmuser created the topic: Nested for loop in Linux Shell Script
As you see the if statement can nested, similarly loop statement can be nested. You can nest the for loop. To understand the nesting of for loop see the following shell script.
$ vi nestedfor.sh
for (( i = 1; i <= 5; i++ )) ### Outer for loop ###
do
for (( j = 1 ; j <= 5; j++ )) ### Inner for loop ###
do
echo -n "$i "
done
echo "" #### print the new line ###
done
Run the above script as follows:
$ chmod +x nestedfor.sh
$ ./nestefor.sh
1 1 1 1 1
2 2 2 2 2
3 3 3 3 3
4 4 4 4 4
5 5 5 5 5
Here, for each value of i the inner loop is cycled through 5 times, with the varible j taking values from 1 to 5. The inner for loop terminates when the value of j exceeds 5, and the outer loop terminets when the value of i exceeds 5.
Following script is quite intresting, it prints the chess board on screen.
$ vi chessboard
for (( i = 1; i <= 9; i++ )) ### Outer for loop ###
do
for (( j = 1 ; j <= 9; j++ )) ### Inner for loop ###
do
tot=`expr $i + $j`
tmp=`expr $tot % 2`
if [ $tmp -eq 0 ]; then
echo -e -n "\033[47m "
else
echo -e -n "\033[40m "
fi
done
echo -e -n "\033[40m" #### set back background colour to black
echo "" #### print the new line ###
done
Run the above script as follows:
$ chmod +x chessboard
$ ./chessboard
Above shell script cab be explained as follows:

Execute Command from Linux to Windows machine
scmuser created the topic: Execute Command from Linux to Windows machine
Hi,
Could you please help me in my following scenario…
Problem Statement: In one windows machine, I have one application (BusinessObject) file which has to perform some kind of import jobs upon getting parameters on command line.
The command to execute this import statement in windows is:
java -jar biarengine.jar <
As part of automation in my project, I am trying to run this command along with parameter from Linux machine. I mean to say when I fire these command from Linux machine, it should get executed in Windows machine.
My questions is: What are the way we have available on which I can fire these command and make sure these got executed in Windows remotely.
Any help on this?

Find files with the Linux find command
rajeshkumar replied the topic: Re: Find files with the Linux find command
This next example is similar, but here I use the -i argument to the grep command, telling it to ignore the case of the characters string, so it will find files that contain string, String, STRING, etc.:
find . -type f -name “*.java” -exec grep -il string {} \;
This command searches through the /usr/local directory for files that end with the extension .html. When these files are found, their permission is changed to mode 644 (rw-r–r–).
find /usr/local -name “*.html” -type f -exec chmod 644 {} \;
This command searches through the htdocs and cgi-bin directories for files that end with the extension .cgi. When these files are found, their permission is changed to mode 755 (rwxr-xr-x). This example shows that the find command can easily search through multiple sub-directories (htdocs, cgi-bin) at one time.
find htdocs cgi-bin -name “*.cgi” -type f -exec chmod 755 {} \;
From time to time I run the find command with the ls command so I can get detailed information about files the find command locates. To get started, this find command will find all the “*.pl” files (Perl files) beneath the current directory:
find . -name “*.pl”
In my current directory, the output of this command looks like this:
./news/newsbot/old/3filter.pl
./news/newsbot/tokenParser.pl
./news/robonews/makeListOfNewsURLs.pl
That’s nice, but what if I want to see the last modification time of these files, or their filesize? No problem, I just add the “ls -ld” command to my find command, like this:
find . -name “*.pl” -exec ls -ld {} \;

rajeshkumar replied the topic: Re: Find files with the Linux find command
To perform a case-insensitive search with the Unix/Linux find command, use the -iname option instead of -name. So, to search for all files and directories named foo, FOO, or any other combination of uppercase and lowercase characters beneath the current directory, use this command:
find . -iname foo
If you’re just interested in directories, search like this:
find . -iname foo -type d
And if you’re just looking for files, search like this:
find . -iname foo -type f

rajeshkumar replied the topic: Re: Find files with the Linux find command
To find all files modified on a certain date, for example, ‘2007-06-07’ the final input is:
find . -type f -newermt 2011-04-20 ! -newermt 2011-04-21
Search for files in your home directory which have been modified in the last twenty-four hours. This command works this way because the time since each file was last modified is divided by 24 hours and any remainder is discarded. That means that to match -mtime
0, a file will have to have a modification in the past which is less than 24 hours ago.
find . -mtime 0

Find Linux Command Collection
rajeshkumar created the topic: Find Linux Command Collection
Find files modified in the last 48 hours, and in current folder and one level below
I believe the correct command is `find -maxdepth 2 -type f -mtime -2
• maxdepth: will tell find to only search in the current folder
• type: will tell find to only list files and not directories
• mtime: will tell find to only list the files modified in the last 24 hours
To find all files modified in the last 24 hours (last full day) in a particular specific directory and its sub-directories:
find /directory_path -mtime -1 –print
To find all files with regular file types only, and modified in the last 24 hours (last full day) in current directory and its sub-directories:
find /directory_path -type f -mtime -1 –print
find . -type f -mtime -1 –print
To find all files that are modified today only (since start of day only, i.e. 12 am), in current directory and its sub-directories:
touch -t `date +%m%d0000` /tmp/$$
find /tmefndr/oravl01 -type f -newer /tmp/$$
rm /tmp/$$
The first command can be modified to specify other date and time, so that the commands will return all files that have changed since that particular date and time.
