The easy way to do it is to note that a Java properties file has the same format as a basic shell script.

However, there’s a trick to it. If you just run the properties file like so:

sh appl.properties

The assignments will be made at the sub-level, then discarded when the properties file (script) ends execution.

So to get the properties in a calling script, you need to use the “source” command:

. appl.properties

Note that the space after the initial dot is very important!

To reference shell variable assignments, you use the “$” to indicate variable substitution.

So, to put it all together:

# #!/bin/sh
# # Sample shell script to read and act on properties
#
# # source the properties:
# . appl.properties
#
# # Then reference then:
# echo "My name is $name and I'm $age years old."

rajeshkumar replied the topic: Re:shell script to run x times
Solution

# Change directory
cd $SWDIR/util

# loop n times and do something in that loop
# (initialize the variable i with 1, then loop as long as i is
# smaller than or equal the variable n. increase i by 1 on
# every looping)
for (( i=1; i<=$n; i++ )) do ./swadm add_process 1 BG Y done

have a script that looks like this

#!/bin/bash

function something() {
echo “hello world!!”
}

something | tee logfile

I have set the execute permission on this file and when I try running the file like this

$./script.sh

it runs perfectly fine, but when I run it on the command line like this

$sh script.sh

It throws up an error. Why does this happen and what are the ways in which I can fix this.

scmuser replied the topic: Re:Whats the difference between running a shell scrip
Running it as ./script.sh will make the kernel read the first line (the shebang), and then invoke bash to interpret the script. Running it as sh script.sh uses whatever shell your system defaults sh to (on Ubuntu this is Dash, which is sh-compatible, but doesn’t support some of the extra features of Bash).

You can fix it by invoking it as bash script.sh, or if it’s your machine you can change /bin/sh to be bash and not whatever it is currently (usually just by symlinking it – rm /bin/sh && ln -s /bin/bash /bin/sh). Or you can just use ./script.sh instead if that’s already working

Perl commandline search and replace

The better option is using perl command line search and replace option. The syntax is the following.

# perl -i.bak -p -e’s/old/new/g’ filename
s/old/new/g

what this does is searches for pattern “old” and replace it pattern “new”.The g option in does the serch n replace globally in the file, otherwise perl searches and replaces only the first instance of the pattern.

Lets explain the options used.

-e option allows you to define Perl code to be executed by the compiler. For example, it’s not necessary to write a “Hello World” program in Perl when you can just type this at the command line.

# perl -e ‘print “Hello World\n”‘

-p option, adds loops around your -e code.It creates code like this:

LINE:
while (<>) {
# your code goes here
} continue {
print or die “-p destination: $!\n”;
}

-i option. Actually, Perl renames the input file and reads from this renamed version while writing to a new file with the original name. If -i is given a string argument, then that string is appended to the name of the original version of the file. For example, to change all occurrences of “PHP” to “Perl” in a data file you could write something like this:

# perl -i -pe ’s/PHP/Perl/g’ file.txt

Perl reads the input file a line at a time, making the substitution, and then writing the results back to a new file that has the same name as the original file — effectively overwriting it. If you’re not so confident of your Perl abilities you might take a backup of the original file, like this:

# perl -i.bak -pe ’s/PHP/Perl/g’ file.txt

Monitor processes continuously. Updates every 3 seconds by default. Displays useful information such as total memory, memory in use, % of total memory used by each process, % cpu usage of each process, and process ID (PID) of each process. Type ‘h’ for help or ‘q’ to quit. To stop (‘kill’) a process, type ‘k’ and enter the PID of the process, then enter the signal for the ‘kill’ command (see below) or press Enter to use the default signal (terminate).

Useful options:
-d Specify time between updates
-u List processes for user
-p List process with ID

You want all the records from list_A supplemented by all the records from list_B for which there is not already a matching name in list A. Mathematically this is:

A + B - {w in B | (w,value) in A }

\

There are many ways of accomplishing this, depending on access and needed efficiencies.

* If you can modify DB1 (with A), then download table B from DB2, upload it to DB1, then extract your data with the appropriate join
* If you can’t modify DB1, then download both A and B and concatenate them to the same stream, with A followed by B. Then sort by the first field. Then process the stream one record at time. Duplicate names will be side-by-side. If the same name appears more than one time, print the first and ignore subsequent records with the same name.

Here is a sample solution to your problem (starting with two lists of names/values)

#!/bin/bash

PrevName="Not a valid name"
echo "$A
$B" | sort -k1 |
while read Name Value
do
if [ "$Name" != "$PrevName" ]; then
echo $Name $Value
fi
PrevName="$Name"
done > outfile

echo “$A
$B” | sort -k1 |
while read Name Value
do
if [ “$Name” != “$PrevName” ]; then
echo $Name $Value
fi
PrevName=”$Name”
done > outfile

Here is the output:

rajeshkumar replied the topic: Re:find application instance directory in unix
To search for anything with the terminal, you can either use the commands locate or which.
Locate is used more like a keyword-based search function. For example, if you type in a terminal:

locate java

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.

Hi,

i am looking for a shell script to find all new files added or modified after a certain date & Time??

Any help?

mnanjala replied the topic: Re:shell script to find all new files added
This should solve the problem

find . -type f -mtime -7 -print

Here,
* -mmin n (modification time in minutes)
* -mtime n (modification time in days)
* -newer file (modification time newer than modification time of file)
* -daystart (adjust start time from current time to start of day)
* Plus alternatives for access time and ‘change’ or ‘create’ time.

Or thinkikng

touch can be used
