如果字符串匹配,则仅打印'+'或' - '(两个文件)

Question

如果找到或不找到字符串,我想只打印'+'o' - '符号.基本上,我有两个文件:

输入文件1(制表符分隔):

HPNK_00457
HPNK_00458
HPNK_00459

输入文件2(制表符分隔):

HPNK_00457  AAA50325    1e-43   437 28  43  83  ATP-binding protein.
HPNK_00458  P25256  8e-43   429 28  43  82  RecName: Full=Tylosin resistance ATP-binding protein tlrC.
HPNK_00458  CAM96590    1e-42   429 27  42  87  ABC transporter ATP-binding protein [Streptomyces ambofaciens].

期望的输出(制表符分隔,维护文件1中的字符串顺序):

HPNK_00457 +
HPNK_00458 +
HPNK_00459 -

这是我一直在使用的,但需要更新:

while read vl; do grep "^$vl      " file2 || printf -- "- -\n" ; done < file1

谢谢,试着每天在这里学习.

Answer 1

这是使用的一种方式awk:

awk 'FNR==NR { a[$1]; next } { print $1, ($1 in a ? "+" : "-" ) }' file2 file1 

结果:

HPNK_00457 +
HPNK_00458 +
HPNK_00459 -
