我有32个文件(由相同的模式命名,唯一的区别是下面写的$ sample数字),我想分成4个文件夹。我试图使用以下脚本来完成这项工作,但脚本无法正常工作,有人可以帮助我使用以下shell脚本吗? - 谢谢
#!/bin/bash
max=8 #8 files in each sub folder
numberFolder=4
sample=0
while ($numberFolder > 1) #skip the current folder, as 8 files will remain
do
for (i=1; i<9; i++)
do
$sample= $i * $numberFolder # this distinguish one sample file from another
echo "tophat_"$sample"_ACTTGA_L003_R1_001" //just an echo test, if works, will replace it with "cp".
done
$numberFolder--
end
答案 0 :(得分:1)
您需要正确使用数学上下文 - (( ))
。
#!/bin/bash
max=8
numberFolder=4
sample=0
while (( numberFolder > 1 )); do # math operations need to be in a math context
for ((i=1; i<9; i++)); do # two (( )), not ( ).
(( sample = i * numberFolder ))
echo "tophat_${sample}_ACTTGA_L003_R1_001" # don't unquote before the expansion
done
(( numberFolder-- )) # math operations need to be inside a math context
done
