Shell Programming and Scripting

Hi,

I am trying to format an existing file to the desired format.

Existing file : abc.txt
2332 |3322 |5534 |5436 |NULL |

Desire file :
QTD GROSS|2332 |3322 |5534 |5436 |


echo "QTD GROSS|" > out.xt
cat abc.txt | cut -c1-52 >> out.txt

I even tried using tee command, but couldn't succeed.
From above script i am getting it as :

QTD GROSS|
2332 |3322 |5534 |5436 |

Instead of
QTD GROSS|2332 |3322 |5534 |5436 |

Can you suggest me how to append the file contents as desired.

Thanks,
Praveen.

echo gives a newline character after a line, use printf instead of echo with the first line.

Code:

printf("QTD GROSS|") > out.xt

Regards

Or:

Code:

echo "QTD GROSS|$(cat abc.txt | cut -c1-52)" > out.txt

However, if your file is going to be more than one line, neither of these is going to work. Then you'll need something more like

Code:

OLDIFS=${IFS}
IFS="
"
while read LINE
do
   echo "QTD GROSS|$(print ${LINE} | cut -c1-52)"
done < abc.txt > out.txt
IFS=${OLDIFS}

If there's only one line in the file:

Code:

IFS=\| read a b c d e < abc.txt
printf "QTD GROSS|%s|%s|%s|%s" "$a" "$b" "$c" "$d"

If there are more lines (but not too many):

Code:

while IFS=\| read a b c d e
do
  printf "QTD GROSS|%s|%s|%s|%s" "$a" "$b" "$c" "$d"
done < abc.txt

If it's a large file, use awk:

Code:

awk -F\| 'printf "QTD GROSS|%s|%s|%s|%s", $1, $2, $3, $4' abc.txt

Maybe this one

Code:

awk -F"|" '{for(i=1;i+1<NF;i++){a=a $i "|"} print "QTD GROSS|"  a}' abc.txt > out.txt

Hi Every one,

Thanks for your suggestions.

The below one helped me to format.

echo "QTD GROSS|`(cat abc.txt | cut -c1-52)`" > out.txt

I am not that Familiar with awk command usage. Will try to put in use others too.
