UNIX for Dummies Questions & Answers

Hi all,

I have used sed command with a file of size 7KB and stored the output to another file.

When i look into the output file, a few file lines at the bottom have got truncated. The sed statement i used is as below. Why does this happen and how to resolve this.

SQL=`sed 's/#,MKT_TBL mkt#/Table_name/g' file1`


Thanks in Advance for ur help.

It could be because of flushing (when writing to your output file) not happening properly.

Try something like,

$sed 's/#,MKT_TBL mkt#/Table_name/gw outputfile' file1

The fault is because you are trying to store the whole output file in an environment variable called $SQL and you have overflowed. There is rarely ever a reason to store more than one record in an environment variable.

The solution by "skmdu" writes straight to disc and is not limited to the maximum size of an environment variable.


A similar method is:

Code:

sed -e 's/#,MKT_TBL mkt#/Table_name/g' file1 > outputfile

BTW. The code you posted does not write to a file.

Methyl & Skmdu,

Thanks a lot for your help.

As Methyl said the problem was bcoz i used a variable to save my ouptut. I used a file for the process and it is working fine now.
