several awk commands consecutively

0

I'm using awk command to extract some datas. The point is that I need to use awk command several times to extract all informations I need and each time when I'm using awk I need create a temp file. My structure looks as below:

awk script1 output.txt > temp1.txt
awk script2 temp1.txt > temp2.txt
awk script3 temp2.txt > Final_output.txt
rm temp1.txt temp2.txt

Is there a way to eliminate the temp files? to execute several commands consecutively?

You might even go further and accept the answer that's been posted in the meantime. Best thing would have been to invite @Hennes to produce an answer out of his comment so you could accept it. This way, everyone will know that your question has been answered satisfactorily. – simlev – 2018-04-12T13:11:06.117

1Is there any reason that you can not use pipes? | – Hennes – 2013-11-23T16:27:53.333

1no reason. I'm new in Linux and I didn't know that's possible;-) Pipes are working, you helped me a lot, thank You! – lucas – 2013-11-23T16:47:08.470

2You might even go further and combine the awk scripts in a single one. – jlliagre – 2013-11-23T17:10:37.937

Your example can be executed using:

awk script1 output.txt | awk script2 | awk script3 > Final_output.txt

If you can combine the scripts (depends on what you will actually do), the line gets even shorter:

awk script123 output.txt > Final_output.txt
