bash-使用前缀文件名将列添加到csv重写标题

我更喜欢使用bash的解决方案，而不是在python中转换为数据帧，因为文件非常大

我有一个CSV文件夹，我想合并成一个CSV。CSV都有相同的标题，但有一些例外，因此我需要用文件名作为前缀重写每个添加列的名称，以跟踪列来自哪个文件

head globcover\u color.csv glds00g.csv

==> file1.csv <==
id,max,mean,90
2870316.0,111.77777777777777
2870317.0,63.888888888888886
2870318.0,73.6
2870319.0,83.88888888888889


==> file2.csv <==
ogc_fid,id,_sum
"1","2870316",9.98795110916615
"2","2870317",12.3311055738527
"3","2870318",9.81535963468479
"4","2870319",7.77729743926775

我不太确定如何做到这一点，但我想我会在某个时候使用该命令。我很惊讶在stackoverflow上找不到类似的问题，但我想在同一行号上有相同id的CSV并不常见

编辑：

我猜出了第一部分

paste-d，*>../rasterjointest.txt

实现了我想要的功能，但需要更换标头

$cat tst.awk
$ cat tst.awk
BEGIN { FS=OFS="," }
FNR==1 {
    fname = FILENAME
    sub(/\.[^.]+$/,"",fname)
    for (i=1; i<=NF; i++) {
        $i = fname "_" $i
    }
}
{ row[FNR] = (NR==FNR ? "" : row[FNR] OFS) $0 }
END {
    for (rowNr=1; rowNr<=FNR; rowNr++) {
        print row[rowNr]
    }
}

$ awk -f tst.awk file1.csv file2.csv
file1_id,file1_max,file1_mean,file1_90,file2_ogc_fid,file2_id,file2__sum

开始{FS=OFS=“，”}
FNR==1{
fname=文件名
子（/\.[^.]+$/，“”，fname）
对于（i=1；iawk运行了整整8分钟，然后内存不足。是否有办法仅处理和输出带有awk的头文件？
paste
似乎可以在不使用太多RAM的情况下正确连接文件创建只包含为我工作的头文件
for i in*；do head-n 1“$i”>heads/$i；done
我添加了一个替代方案，在awk脚本中使用很少的内存，因为几乎所有的工作都是通过粘贴完成的，
$ cat tst.awk
BEGIN { FS=OFS="," }
FNR==1 {
    fname = FILENAME
    sub(/\.[^.]+$/,"",fname)
    for (i=1; i<=NF; i++) {
        $i = fname "_" $i
    }
}
{ row[FNR] = (NR==FNR ? "" : row[FNR] OFS) $0 }
END {
    for (rowNr=1; rowNr<=FNR; rowNr++) {
        print row[rowNr]
    }
}
