Strange Problem in case statement while shift

Leave a comment

By zaq1xsw2

Hi,

Here is my code as below:

test.ksh:
=======

Code:

#!/bin/ksh
option="${1}"
while [ $# -gt 0 ]
do
case $1 in
-f) FILE="${2}"
echo "File name is $FILE"
;;
-d) DIR="${2}"
echo "Dir name is $DIR"
;;
-*)
echo "`basename ${0}`:usage: [-f file] | [-d directory]"
exit 1 # Command to come out of the program with status 1
;;
*) ;;
esac
shift 1
done

While i am running the above script:

Code:

[kanix@voodoo mydir]$ ./test.ksh -f "abc.txt"
File name is abc.txt

The above output is as expected.. But when i am running as below:

Code:

[kanix@voodoo mydir]$ ./test.ksh -f "-abc.txt"
File name is -abc.txt
test.ksh:usage: [-f file] | [-d directory]

the usage code is getting displayed.. which is not expected..

But again when i am providing a space between the quote and hyphen it is again showing the expected result.

Code:

[kanix@voodoo mydir]$ ./test.ksh -f " -abc.txt"
File name is -abc.txt

Please advise why this is happening and how to fix this.. i need to run the code as : ./test.ksh -f “-abc.txt”

Perl Threads Terminating Abnormally.

Leave a comment

By Azrael

I’ve used threads before, but not with Perl. Tried looking these errors and using ‘join’ instead of ‘detach’ with no luck. Here is the code I am currently using:

Code:
#!/usr/bin/perl -w

use warnings;
use threads;
use threads::shared;

$Linux='Linux';
$Greek='Greek';

# Declare threads with their sub-routines
my $thr1 = threads->create(&work1);

sub work1 {
open(FILE,"/home/mine/text");
if (grep{/$Greek/} ){
print "/home/mine/text exists!n"
}else{
system("echo '' > /dev/null");
}
close FILE;
$thr1->detach();
}

my $thr2 = threads->create(&work2);

sub work2 {
$filename = "/home/mine/kcron";
if (-e $filename) {
print "/home/mine/kcron exists!n";
}else{
system("echo '' > /dev/null");
}
$thr2->detach();
}

my $thr3 = threads->create(&work3);

sub work3 {
open(FILE,"/home/mine/geek.txt");
if (grep{/$Linux/} ){
print "/home/mine/geek.txt exists!n";
}else{

How to replaces a value in a file after a particular string using perl?

Leave a comment

By praveen265

I need to replace the value of notifications_enabled to 0 if the value already set to 1 and vice versa(not the other values and spaces remain same after the value changed). I tried the below program for that. Can any one help me out.

file:test.cfg
define host {
hostgroups linux-servers
max_check_attempts 5
check_interval 5
retry_interval 1
notification_interval 60
notifications_enabled 1
}

script:
#!/usr/bin/perl
use strict;
use vars qw( @value $status $line);

@value = `grep -i notifications_enabled /root/test.cfg`;
open(FILE,”/root/test.cfg”) || die unable to open the config_file;
while ($line = )
{
chomp $line;
@value = `grep -i notifications_enabled /root/test.cfg`;
$status = (split(/s{2,}/,$value[0]))[1];
}
print “$statusn”;
close(FILE);

open(FILE,”>>/root/test.cfg”) || die unable to open the config_file;
while ( $line = )
{
print “$status”;
if ( $status == 1) {
$status = 0;
}
}
close(FILE);

Find and split the list of files with suffiz of seg**

Leave a comment

By Satish Shettar

Hi,.

I am writing a script to get the new files and split them.

Requirement
Find the new files under the path “/wload/scmp/app/data/OAS” (There are 5 sub folders).
Gunzip the files which are having .gz suffix.
Put the list of files in the filename in the format “fiels_to_split_2013012911300.txt where as the numeric part is date and time.
Perform the split command on the files to split each file containing 50000 lines.
The output of the split filename should have the same file with suffix seg** where ** can be either numbers or alphabets.

I got the code from Pikk45 and tried to add/modify as per the need.

find /wload/scmp/app/data/OAS -name “*.gz” -size +100000000 -type f -mtime -1 -exec gunzip {} ;
FILENAME=new_fiels_to_split$(date +”%Y%m%d%H%M”).txt
find /wload/scmp/app/data/OAS -type f -mtime -1 > /wload/scmp/app/data/OAS/$FILENAME
FILES=/wload/scmp/app/data/OAS/$FILENAME
FIRST=1
FILE=1
SPL=50000
while read file; do
if [ -e “${FILE}” ]; then
while [ $SPL -le `wc -l $FILES`]
do
sed -n ‘$FIRST,$SPLp’ $FILES > $FILES.seg{$FILE}
fi
done < ${FILES}
FIRST=`expr $FIRST + 50000`
SPL=`expr $SPL + 50000`
FILE=`expr $FILE + 1`
done

for example
the source files


-rw-rw-r– 1 scmpadm scmpuser 755861762 Jan 26 20:04 activity.log.20130125.gz
-rw-rw-r– 1 scmpadm scmpuser 0 Jan 26 20:05 trigger.activity.log.20130125
-rw-rw-r– 1 scmpadm scmpuser 913911244 Jan 27 20:24 activity.log.20130126.gz
-rw-rw-r– 1 scmpadm scmpuser 0 Jan 27 20:25 trigger.activity.log.20130126
-rw-rw-r– 1 scmpadm scmpuser 329351168 Jan 28 19:10 activity.log.20130127.gz

After gunzip

-rw-rw-r– 1 scmpadm scmpuser 3012939863 Jan 28 19:10 activity.log.20130127

Files after split

-rw-rw—- 1 scmpadm scmpuser 49877675 Jan 29 07:04 activity.log.20130127.segaa

How to change time stamp with touch command?

Leave a comment

By bioinfo

Hi,

I wish to change time stamp of a directory with all its subdirectories and files on server.
I am able to find following two ways but want to know which will be the better one. I have not tried anyone of them because I am not sure if it can effect my data:

Code:
find * -type d -exec touch '{}/.gitkeep' ;

Code:

$ bash recursive_touch.sh MyProject .gitkeep

SOURCE_DIR=$1
FILE=$2

recursive_touch() {
for dir in *
do
if [ -d $dir ]
then
cd $dir; recursive_touch
fi
touch $FILE
done
}

cd $SOURCE_DIR; recursive_touch

Using sed in a for loop

Leave a comment

By plumb_r

Hello
I have a group of files

Code:
a1.profile a2.profile a3.profile a4.profile b1.profile b2.profile b3.profile b4.profile

These files all have the same first line with a value s1 atop the columns

Code:
s1_context s1_ref s1_sample s1_% etc

I am trying to use sed in a for loop to replace the s1 in the header of each each file with the initial part of the filename with something like

Code:
for FILE in a1 a2 a3 a4 b1 b2 b3 b4
do
sed -i.bak "1s/s1/$FILE/g" $FILE.profile > $FILE.profile.header
done

But I am not getting the desired output. I just get $FILE in the header instead.
Thanks
