Network AWK Script Issue insert newline for a regular expression match
Hi ,

I am having an issue with the Awk script to insert newline for a regular expression match

Having a file like this

Code:
FILE1
####################
RXOER , RXERA , RXERC , RXERD
.RXEA(RXBSN), RXERD , REXCD
input RXEGT
buffer RXETRY 
#######################

Want to match the RXE Regular expression in the FILE1 and insert a new line after the expression but with some conditions as shown in output


Code:
Output should be like this 
######################
RXOER,
RXERA , 
RXERC , 
RXERD
.RXEA(RXBSN)
RXERD ,
REXCD
input RXEGT
buffer RXETRY 
###########################

I am trying this script like this
awk '{gsub(/RXE/,"RXE\n"}' FILE1

but not getting the output as shown in the output file
Tried to Split it also but could not able to work with Split command of Awk

Please help me out

Thanks
Jaita

Issue with the Regular pattern match
Hi Bartus .

Thanks for the Reply
But I want to match the Regular expression RXE and on the basis of the match it should insert the newline but selective matching should be there on the basis on conditions

Matching the RXE and inserting newline to after matching with the pins having RXE

Thanks
Jaita

But in your sample input you matched "RXO" and "REX" and inserted newline after them as well.

Network awk issue
Thats True

its a sample file from a very big File
I need to match only RXE and wherever it matches RXE , it should insert newline

For example
Reframing the code once again for more clarification

Code is like this

Code:
 
ROXER , RTOEX , RXERT , RXERY , RXERU
.RAEY(TXBSIM) , .RREU(TXDSIN),  .RXEY(TSTY) , .RXEI(TSTR)
input RXETY
output RXEUI

Output should be like this

Code:
 
ROXER , RTOEX , 
RXERT , 
RXERY , 
RXERU
.RAEY(TXBSIM) , .RREU(TXDSIN),  
.RXEY(TSTY) ,
.RXEI(TSTR)
 
input RXETY
 
output RXEUI

Thanks
Jaita
