bash: /bin/ls: Argument list too long

I need to make a list of a large number of files (40,000 files) like below:

ERR001268_1_100.fastq  ERR001268_2_156.fastq  ERR001753_2_78.fastq
ERR001268_1_101.fastq  ERR001268_2_157.fastq  ERR001753_2_79.fastq
ERR001268_1_102.fastq  ERR001268_2_158.fastq  ERR001753_2_7.fastq
ERR001268_1_103.fastq  ERR001268_2_159.fastq  ERR001753_2_80.fastq

my command is: ls ERR*_1_*.fastq |sed 's/\.fastq//g'|sort -n > masterlist However error is: bash: /bin/ls: Argument list too long

However can I solve this problem? Any other way to make list like this by perl/python?

thx

You should be able to replace ls ERR*_1_*.fastq with find . -name "ERR*_1_*.fastq".
This way, you can avoid having the wildcard expand into a huge argument list.

(The find output will include a leading "./", e.g. ./ERR001268_1_100.fastq . If that's undesirable, you can get rid of it with another sed command later in the pipeline.)
