bash - gnu并行中的两对双引号冲突

Question

由于并行双引号与 OFS="\t"的双引号冲突，命令失败。有什么建议可以让它发挥作用吗？谢谢!

ls *bed | parallel -j 10 "intersectBed -a good-genes.gff -b {} -c | awk 'BEGIN{OFS="\t";} {print $1,$9,$4,$5,$7,$10}' > test.txt"

Answer 1

因为你有“外部”双引号，你也会遇到 awk $ 变量的问题。我会把它分成几 block :

awk_body='BEGIN{OFS="\t";} {print $1,$9,$4,$5,$7,$10}'
ls *bed | parallel -j 10 "intersectBed -a good-genes.gff -b {} -c | awk '$awk_body' > test.txt"
