- 使用-v选项
head -n 3 /etc/passwd | awk -v test="hello" -F: '{print test,$1}'
加三个变量
awk -v a=${array[0]} -v b=${array[1]} -v c=${array[2]} '{if(($1==a)&&($4==b)&&($5==c))print}' ..
-
在BEGIN{}模式自定义变量
head -n 3 /etc/passwd | awk -F: 'BEGIN{test="hello"}{print test,$1}'
-
?
pa=pa01t1
sample=pa01_tumor1
cat result_${pa}_quickmode/${sample}_R1_clean${sample}_R2_clean_HPV_HumanGene_Annotated_Cyto.txt | awk '{print $2}' | less
可以识别该文件的第二列?
cat result_${pa}_quickmode/${sample}_R1_clean${sample}_R2_clean_HPV_HumanGene_Annotated_Cyto.txt | awk -v a=$sample -F: '{print a,$2}' | less
不识别第二列?
暂时解决,双重awk:
在文件末尾加一列一样的值,例如-/./*
awk '{print $0,"cwy"}' test1.txt > test2.txt
cut -f lastclonum test2.txt #failed
sed -i 's/.*\s//g' test2.txt # get the last colnum
