Dear All

```
   I have two text files File1.txt and File2.txt . I am concatenating the two files and making it as single file Cat_File.txt. Now i need to keep joined file in two different path. that is I need to use cat command only once ,but store joined file in two different locations. Since file size is huge, I trying to avoid second cat or move or copy.

```

Command used for cat  
-----------------------  
cat File1.txt File2.txt \> /file\_path/Cat\_File.txt

may be, you can try:  
cat File1.txt File2.txt | tee file\_path1/Cat\_File.txt \> file\_path2/Cat\_File.txt

You can use tee to achieve this as below.

```nohighlight
cat infile1 infile2 | tee outfile1 > outfile2

```

Hi

You can use following command  
cat a b \> /root/c  
This will copy all the data in both the files a and b into the file c..  
If file c is not present the this command will make it and append data into it...
