1. grep 时 Binary file (standard input) matches
Plus -a solve
v_rowline_319=`cat ${v_logfile}_319 | grep -a "totalLine:" | awk -F ':' '{print $8}' | awk 'END {print}'`2. shell -eq and = difference
-eq
for INTEGER type comparison.
INTEGER1 -eq INTEGER2
INTEGER1 is equal to INTEGER2
=
Apply as compared to the STRING type, but also for INTEGER type comparison.
= STRING2 STRING1
at The strings are equal is
STRING1! = STRING2
at The strings are not equal is
Integer1 -eq Integer2
Integer1 IS equal is to Integer2
