regex - how to extract a part of header in Fasta file by using Linux command -

i have fasta file unique header,i extract part of header using regular expression in unix.

for example fasta file start header:

>jgi|penbr2|47586|fgenesh1_pm.1_#_25

and extract last part of header like:

>fgenesh1_pm.1_#_25

actually use regular expression in vim editor did not work:

:%s/^([^|]+\|){3}//g

:%s/^([a-z][0-9]+\|){3}//g

i appropriate if give me suggestion.

you can use sed:

sed -e 's/>.*|/>/' fasta-file

i.e. between > , | replaced >.
