我在文件上使用以下命令来根据 chr#(不同的染色体编号)提取几行。这只是正在处理的一个文件。我有 8 个这样的文件,对于每个文件,我必须对 chr 执行此操作(1 到 22,然后是 chrX 和 chrY),我没有使用任何循环,我单独执行此操作,但如果您看到我希望标头完好无损我的每一个输出。如果我单独执行,我会在输出中得到标头,但如果正在运行,但如果我一起运行所有 8 个文件的脚本(就像脚本中一个接一个的 8*24 命令),则输出没有任何标头。你能告诉我为什么会发生这种情况吗?

我正在使用 qsub 将其作为作业运行,因此脚本的结构如下所示。如果我单独执行命令,它会起作用,但如果我像这样运行它们,标题不会打印在输出文件中,即“;”似乎不被认可。我尝试使用 qsub filename.sh 和 sh filename.sh 来运行它。我发现使用 sh filename.sh 标题会打印在控制台中。所以肯定是';'之前的命令文件中未写入分号。我怎样才能摆脱这个问题。
期望的输出:

答案1
你需要这样的东西:
{ head -n1 S_313_IPS_S7995.coverage.sample_interval_summary;
grep "chr1" S_313_IPS_S7995.coverage.sample_interval_summary; } >S_313_IPS_S7995.chr1.coverage
或者
awk 'NR==1 || /chr1/' S_313_IPS_S7995.coverage.sample_interval_summary >S_313_IPS_S7995.chr1.coverage
问题是重定向仅影响一个命令。为了获得重定向中head
和的输出,必须对它们进行分组。grep
但awk
这里可能是更好的选择。
