Hi
I tried to extract 19 characters (default) enclosed with in tag from a file using cut command. If the characters comprises of double space, the cut command gives the output with a single spacing.
file 1
<name>Kumar Rajasekaran</name>
cut -c7-26 "file1"
the out put i received is
Kumar Rajasekaran
Expected output
Kumar Rajasekaran
Please guide me.
Thanks
Will this work for you?
$ echo '<name>Kumar Rajasekaran</name>' | awk -F "<name>|</name>" '{print $2}'
Kumar Rajasekaran
$
This will preserve the spaces.
Well, I tried with cut and it reserves the space too.:rolleyes:
And try with sed too..
echo "<name>Kumar Rajasekaran</name>" | sed 's/<name>\(.*\)<\/name>/\1/'
Thanks,
Please have a look on my code. Please let me know how to use awk command as mentioned above.
source file input
name>Rajesh vadakar IIT Chennai </name>
Expected output
Rajesh vadakar IIT Chennai
c_line="/apps/source.txt"
targetfile="result.txt"
var1=0
while read c_line
do
var1=`grep -c "IIT Chennai" $c_line`
echo $var1 >> $targetfile
if [ $var1 -ge 1 ]
then
val=`cut -c6-37 $c_line`
echo $var >> $targetfile
fi
done<${c_line}
Please update me as earliest.
Thanks

my above code is also not working. Please correct my mistake.
replace
val=`cut -c6-37 $c_line`
with
val=`echo $$c_line | cut -c6-37 `

Hi,
Still its not working. It is considering newspace as blank line. so the above name tag value is spiltted in to differents columns.
pleasre review my code and correct me
Had an extra $ in my code above
val=`echo $c_line | cut -c6-37 `
HI
i included as u said. But while reading itself, it is suppressing blank spaces more than one occurance to one. so i am getting wrong data. Please review my code
c_line="/apps/source.txt"
targetfile="result.txt"
var1=0
while read c_line
do
var1=`grep -c "IIT Chennai" $c_line`
echo $var1 >> $targetfile
if [ $var1 -ge 1 ]
then
val=`cut -c6-37 $$c_line`
echo $var >> $targetfile
fi
done<${c_line}
Have you getting any error?
can you post the content of "/apps/source.txt" ?
As u said, i included, but in vain. Please correct me if i am doing wrong.
while read c_line
do
echo $c_line >> $targetfile
var1=`grep -c "IIT Chennai" $c_line`
if [ $var1 -ge 1 ]
then
val=`echo $$c_line | cut -c6-37 `
echo $var >> $targetfile
fi
done<${c_line}]
Ok, plz tell me what is the I/P contents and what is the expected O/P. We will provide you the solution depending on that.
i am not getting anything the final.txt file. please find the execution result.
$. ./file.sh
grep: can't open <Record><s

My input file has the following data
<Record><sno>1</sno><empid>E0001</empid><name>Rejsh suderam</name><college>IIT Chennai </college>
while read c_line
You are modifying c_line variable. and now this contains the each line of the input file.
and grep expects a filename
use another variable name in while.
And use like this:
echo $line_var | grep ....
I have space in the input tag college. The tag college holds the value as "IIT Chennai " and i want the output exaclty with the spaces given in input between IIT and chennai
Expected OUTPUT
---------------
"IIT Chennai"
Again, can't you use awk ??
$ awk -F "<name>|</name>" '{print $2}' x
Rejsh suderam
Rejsh suderam
Rejsh suderam
Rejsh suderam
$ cat x
<Record><sno>1</sno><empid>E0001</empid><name>Rejsh suderam</name><college>IIT Chennai </college>
<Record><sno>1</sno><empid>E0001</empid><name>Rejsh suderam</name><college>IIT Chennai </college>
<Record><sno>1</sno><empid>E0001</empid><name>Rejsh suderam</name><college>IIT Chennai </college>
<Record><sno>1</sno><empid>E0001</empid><name>Rejsh suderam</name><college>IIT Chennai </college>
$

If "IIT Chennai":
$ awk -F "<college>|</college>" '{print $2}' x
IIT Chennai
IIT Chennai
IIT Chennai
IIT Chennai
$
I did as you mentioned. Please review.
while read c_line
do
echo $c_line >> $targetfile
var1=`echo $c_line | grep -c "IIT Chennai"`
#echo $var1 >> $targetfile
if [ $var1 -ge 1 ]
then
#val=`cut -c7-75 $$c_line`
#val=`echo $$c_line | cut -c78-94 `
val=`awk -F "<college>|</college>" '{print $2}'`
echo $var >> $targetfile
fi
done<${c_line}
I am not getting any output while executing the script file.
#cat source.txt
<Record><sno>1</sno><empid>E0001</empid><name>Rejsh suderam</name><college>IIT Chennai </college>
output
--------
$ cat final.txt
$
while read line;
do if [ `echo $line | grep -c "IIT Chennai"` -gt 0 ]; then
var=`echo $line | sed 's/.*<college>\(.*\) <\/college>$/\1/'`;
echo $var;
fi;
done< file

You don't need to read the file if you are using awk.
if you want the output as
<input line 1>
IIT Chennai
<input line 2>
IIT Chennai
try just:
awk -F "<college>|</college>" '{print $0"\n"$2}' source.txt > final.txt
You can as well do just but i wrote the script using sed above just as yu wanted.
sed 's/.*<college>\(.*\) <\/college>$/\1/' file
