sh: BEGIN:  not found.
sys,root # { print $8, "\t", $3}
> END { print " - DONE -" }

what you actually trying to do ?

parsing any file ?

how the file looks like ?

Code:
 
awk 'BEGIN { print SNA_DB_UPG.list "|" }{ print $8, "\t", $3}END { print " - DONE -" }' filename.txt

Thanks itkamaraj,

I have to do small change in the code (tiny project)

There is a file name SNA_DB_UPG.list which has a format:
Code:
#
#MNT4   ##R9.1.1.4
#R950   ##R9.5.0
#R9501  ##R9.5.0.1
#R960   ##R9.6.0
#############################################################
#------------MNT4-----------
MNT4|00010|msp125867|$PLATFORM_BIN/reload_PA_TABLE 1620_LM
MNT4|00020|msp127060|$PLATFORM_BIN/reload_PA_TABLE 1626_LMT
#------------R950-----------
R950|00010|msp126597|$PLATFORM_BIN/reload_PA_TABLE 1830PSS_32
R950|00020|msp126860|$PLATFORM_BIN/reload_ctl neModifier
R950|00030|msp126856|$UPG_BIN_DIR/cv950_SNAupg_001.sh
#------------R9501-----------
R9501|00010|msp127217|$PLATFORM_BIN/reload_ctl neModifier
R9501|00020|msp127540|$PLATFORM_BIN/reload_ctl layerRateMap
R9501|00030|msp127060|$PLATFORM_BIN/reload_PA_TABLE 1626_LMT
#------------R960-----------
R960|00010|msp131228|$PLATFORM_BIN/reload_ctl neModifier
R960|00020|msp131233|$UPG_BIN_DIR/cv960_NWCupg_001.sh

From here I need to read this file and create two seperate file say SPEC_INSTR.list
Code:
MNT4|00010|msp125867|$PLATFORM_BIN/reload_PA_TABLE 1620_LM
MNT4|00020|msp127060|$PLATFORM_BIN/reload_PA_TABLE 1626_LMT
R950|00010|msp126597|$PLATFORM_BIN/reload_PA_TABLE 1830PSS_32
R950|00020|msp126860|$PLATFORM_BIN/reload_ctl neModifier
R950|00030|msp126856|$UPG_BIN_DIR/cv950_SNAupg_001.sh
R9501|00010|msp127217|$PLATFORM_BIN/reload_ctl neModifier
R9501|00020|msp127540|$PLATFORM_BIN/reload_ctl layerRateMap
R9501|00030|msp127060|$PLATFORM_BIN/reload_PA_TABLE 1626_LMT
R960|00010|msp131228|$PLATFORM_BIN/reload_ctl neModifier
R960|00020|msp131233|$UPG_BIN_DIR/cv960_NWCupg_001.sh

and the other file with DISTINCT_MODEL.list
Code:
$PLATFORM_BIN/reload_PA_TABLE 1620_LM
$PLATFORM_BIN/reload_PA_TABLE 1626_LMT
$PLATFORM_BIN/reload_PA_TABLE 1830PSS_32
$PLATFORM_BIN/reload_ctl neModifier
$UPG_BIN_DIR/cv950_SNAupg_001.sh
$PLATFORM_BIN/reload_ctl neModifier (remove it - only distinct)
$PLATFORM_BIN/reload_ctl layerRateMap
$PLATFORM_BIN/reload_PA_TABLE 1626_LMT (remove it - only distinct)
$PLATFORM_BIN/reload_ctl neModifier (remove it - only distinct)
$UPG_BIN_DIR/cv960_NWCupg_001.sh

After this I need to execute the SPEC_INSTR.list first command/line i.e.
Code:
MNT4|00010|msp125867|$PLATFORM_BIN/reload_PA_TABLE 1620_LM

Only If the fourth field i.e.
Code:
$PLATFORM_BIN/reload_PA_TABLE 1620_LM

is present in the SPEC_INSTR.list file. If present after executing this command we need to delete the entry of 1620_LM from the SPEC_INSTR.list file
and further execute the same until the last command/line of the SPEC_INSTR.list file.
