Interpretation needed for gawk command

Shell Programming and Scripting
1

Hi All

I am running a insatll script in linux which installs the project.
Could you please help in interpreting this command

gawk '{ if (substr($1,0,1) == "\047") gsub("^\047+|\047+$", "", $1); print }'
 
where $1 = BBME

Thanks

It will remove single quotes at the beginning and end if found at the beginning of the string.
\047 = '

root@bt:/tmp# cat file
'BBME'

root@bt:/tmp# awk '{ if (substr($1,0,1) == "\047") gsub("^\047+|\047+$", "", $1); print }' file
BBME
