Tried using awk '{print $0}' RS='==' data but details above ======== is still there and with a big gap.

Update:

So everything is now in place. However, i'm having a hard time concatenating the file. I have two files named sw_name and final_sw_name which consist of the data above and is being passed on to a variable.

When I tried to echoed it using this command
echo -e "$sw_name" > ${SW_TEMP}/TP; echo -e "\n final_sw_name >> ${SW_TEMP}/TP The $sw_name is being echoed on the file but not $final_sw_name.

Should be like this:

btw, is there a way i can grep this part `switchName: GBL_A_SW1` then next is this `awk 'p; /^=+$/{p=1}'`.. Tried a different combination but i couldn't get it. — gafm, Jul 22 '19 at 15:13
Yes you can use: `awk 'p || /^switchName/ || p; /^=+$/{p=1}' file` — anubhava, Jul 22 '19 at 15:16
so I was to achieve what is required however when i put it on a variable and echoed it. It's not printing as expected. It's printing but not with newline ` 0 3 0 2a0040 id N8 Online FC E-Port (Trunk port, master is Slot 3 Port 1 ) 1 3 1 2a0140 id N8 Online FC E-Port 10:00:c4:f5:7c:2c:1d:d8 "GBL_A_BAS384B" (downstream)(Trunk master) 2 3 2` — gafm, Jul 23 '19 at 14:24
Code and data is not readable in comments. Better you edit your question and show your input data with attempted code. — anubhava, Jul 23 '19 at 14:31
I don't understand how your command `echo -e "$sw_name" > ${SW_TEMP}/TP; echo -e "\n final_sw_name >> ${SW_TEMP}/TP The $sw_name` is related to my suggested `awk` command. — anubhava, Jul 23 '19 at 15:42

Try:

sed '0,/========/ d' data

It deletes from the stream lines in range [0 .. the first line matched by regex ========] and then prints the rest of the stream normally.

Note that 0 start line is a GNU extension which means it may not be available on some systems. If you want to have a portable script, better use index 1 instead.

sed '1,/========/ d' data

The second solution won't work if characters ======= are in the first line, though.

If this may be the case, you can just insert an empty line at the start of the stream.

{ printf '\n' ; cat data ; } | sed '1,/========/ d'

Notice that `0` as an address is a GNU sed extension. – Benjamin W. Jul 22 '19 at 13:18

Not it won't work if the match is on the first line; I meant more that you should probably point out that it's a GNU extension. – Benjamin W. Jul 22 '19 at 14:29
@BenjaminW. This solution got more complicated than I've intended. Anyway, I hope it's all right now. – Piotr Siupa Jul 22 '19 at 15:22

Defining `RS` to be an extended regular expression is an extension of GNU awk. According to Posix, `RS` is only a single character. – kvantour Jul 22 '19 at 13:41

Print everything below after a trailing "========"
