Solved: Hi guys. GREP (sigh)... I need to remove the empty lines after datamerge for certain products. The checkbox to delete blank lines will not work in - 10872224
When grep stops after NUM matching lines, it outputs any trailing context lines. When the -c or --count option is also used, grep does not output a count greater than NUM. When the -v or --invert-match option is also used, grep stops after outputting NUM non-matching lines. -o,...

1. -A NUM,--after-context=NUM 除了列出符合行之外,并且列出后NUM行。 ex: $ grep -A 1 panda file (从file中搜寻有panda样式的行,并显示该行的后1行) 2. -a或--text grep原本是搜寻文字文件,若拿二进制的档案作为搜寻的目标, 则会显示如下的讯息: Binary file 二进制文件名 matches 然后结束。
The exit status is 0 if selected lines are found, and 1 if not found. If an error occurred the exit status is 2. 即,grep 命令在所给文件中查找特定模式的字符串,可以提供多个文件名,在多个文件中查找。 如果没有提供文件名,则读取标准输入。
