substitute file names using rename

问题

I want to rename files names by substituting all the characters starting from "_ " followed by eight capital letter and keep only the extension.

4585_10_148_H2A119Ub_GTCTGTCA_S51_mcdf_mdup_ngsFlt.fm
4585_10_148_H3K27me3_TCTTCACA_S51_mcdf_mdup_ngsFlt.fm
4585_27_128_Bap1_Bethyl_ACAGATTC_S61_mcdf_mdup_ngsFlt.fw
4585_32_148_1_INPUT_previous_AGAGTCAA_S72_mcdf_mdup_ngsFlt.bw

expected output

4585_10_148_H2A119Ub.fm
4585_10_148_H3K27me3.fm
4585_27_128_Bap1_Bethyl.fm
4585_32_148_1_INPUT_previous.fm

回答1:

Try this:

for f in *; do
    target=$(echo "${f}" | sed -E 's/_[[:upper:]]{8}.*\././')
    mv "${f}" "${target}"
done

The key thing is the -E argument to sed, since it enables expanded regular expressions.

You can also use rename (a.k.a. prename or Perl rename) like this:

rename --dry-run 's|_[[:upper:]]{8}.*\.|.|' *

Sample Output

'4585_10_148_H2A119Ub_GTCTGTCA_S51_mcdf_mdup_ngsFlt.fm' would be renamed to '4585_10_148_H2A119Ub.fm'
'4585_32_148_1_INPUT_previous_AGAGTCAA_S72_mcdf_mdup_ngsFlt.bw' would be renamed to '4585_32_148_1_INPUT_previous.bw'

Remove the --dry-run and run again for real, if the output looks good.

This has several added benefits:

that it will warn and avoid any conflicts if two files rename to the same thing,
that it can rename across directories, creating any necessary intermediate directories on the way,
that you can do a dry run first to test it,
that you can use arbitrarily complex Perl code to specify the new name.

On a Mac, install it with homebrew using:

brew install rename

You may try this.

for i in *.fm; do mv $i $(echo $i | sed 's/_GTCTGTCA_S51_mcdf_mdup_ngsFlt//g'); done;
for i in *.fm; do mv $i $(echo $i | sed 's/_TCTTCACA_S51_mcdf_mdup_ngsFlt//g'); done;
