ksh sed - Extract specific lines with mulitple occurance of interesting lines
Data file example

Quote:
primary
Factory CTS 1.9.6(2) P1
*Slot 1 CTS 1.9.6(2) P1
Slot 2 CTS 1.7.1(4864) P1
loads file information
Factory (cmterm-CTS.1-9-6-2R-K9.P1)
CTS: CTS.1-9-6-2R-K9.P1.sbn
Touch: CTSDEV.1-9-6-2R-K9.P1.SPA
Slot 1 (cmterm-CTS.1-9-6-2R-K9.P1)
CTS: CTS.1-9-6-2R-K9.P1.sbn
Touch: CTSDEV.1-9-6-2R-K9.P1.SPA-G
Slot 2
No loads file
I look for primary and * to isolate the interesting slot number.

Code:
slot=`sed '/^primary$/,/\*/!d' filename | tail -1 | sed s'/*//' | awk '{print $1" "$2}'`

Now I want to get the Touch line for only the associate slot number, in this case, because the asterisk indicates the interesting slot, "Slot 1"

Code:
sed -n '/\s+"$gslot"/p; /Touch:/p'

Output
Quote:

Slot 1
Touch: CTSDEV.1-9-6-2R-K9.P1.SPA
Touch: CTSDEV.1-9-6-2R-K9.P1.SPA-G
My question is :
How do I get only the Touch line following the Slot 1 line ? (marked that interesting line with a "-G"

Ofcourse I could have missed something, ... looking through books and the web but I havent found anything that addresses this issue.

NAME

       enum_mac80211_rate_control_flags - per-rate flags set by the Rate Control algorithm.

SYNOPSIS

       enum mac80211_rate_control_flags {
	 IEEE80211_TX_RC_USE_RTS_CTS,
	 IEEE80211_TX_RC_USE_CTS_PROTECT,
	 IEEE80211_TX_RC_USE_SHORT_PREAMBLE,
	 IEEE80211_TX_RC_MCS,
	 IEEE80211_TX_RC_GREEN_FIELD,
	 IEEE80211_TX_RC_40_MHZ_WIDTH,
	 IEEE80211_TX_RC_DUP_DATA,
	 IEEE80211_TX_RC_SHORT_GI,
	 IEEE80211_TX_RC_VHT_MCS,
	 IEEE80211_TX_RC_80_MHZ_WIDTH,
	 IEEE80211_TX_RC_160_MHZ_WIDTH
       };

CONSTANTS

       IEEE80211_TX_RC_USE_RTS_CTS
	   Use RTS/CTS exchange for this rate.

       IEEE80211_TX_RC_USE_CTS_PROTECT
	   CTS-to-self protection is required. This is set if the current BSS requires ERP protection.

       IEEE80211_TX_RC_USE_SHORT_PREAMBLE
	   Use short preamble.

       IEEE80211_TX_RC_MCS
	   HT rate.

       IEEE80211_TX_RC_GREEN_FIELD
	   Indicates whether this rate should be used in Greenfield mode.

       IEEE80211_TX_RC_40_MHZ_WIDTH
	   Indicates if the Channel Width should be 40 MHz.

       IEEE80211_TX_RC_DUP_DATA
	   The frame should be transmitted on both of the adjacent 20 MHz channels, if the current channel type is NL80211_CHAN_HT40MINUS or
	   NL80211_CHAN_HT40PLUS.

       IEEE80211_TX_RC_SHORT_GI
	   Short Guard interval should be used for this rate.

       IEEE80211_TX_RC_VHT_MCS
	   VHT MCS rate, in this case the idx field is split into a higher 4 bits (Nss) and lower 4 bits (MCS number)

       IEEE80211_TX_RC_80_MHZ_WIDTH
	   Indicates 80 MHz transmission

       IEEE80211_TX_RC_160_MHZ_WIDTH
	   Indicates 160 MHz transmission (80+80 isn't supported yet)

DESCRIPTION

       These flags are set by the Rate control algorithm for each rate during tx, in the flags member of struct ieee80211_tx_rate.
