Not digging too deep, I can see that
- your single quoting of the sed commands is consistently wrong - the entire respective command needs to be quoted.
- the redirection into the to-be-modified file truncates it before anything is read from it, so I'm very surprised that only several files should be completely blank.
- running 7 seds (i.e. creating 7 processes) for 4000 file is resource hungry and may become somewhat slow.
- running a for loop from 0 to 4000 with i the loop variable, why do you use another j variable?

How about
Code:
for FN in clus*phy; do sed '/aver\|anid\|anig\|acar\|azon\|awen\|akaw/ s/_[^ ]*//' $FN > ${FN}.tmp; done

Move the .tmp files to the origial ones when happy.

rubibtex

rubibtex(1)							       teTeX							       rubibtex(1)

NAME

       rubibtex - make a bibliography for (La)TeX using Russian letters as item names

SYNOPSIS

       rubibtex BASENAME

DESCRIPTION

       rubibtex is used to run bibtex(1) on auxiliary files with Russian characters in item names (citation keys).  It is part of the T2 package.

       rubibtex  copies the auxiliary file to /tmp, uses sed(1) to convert Cyrillic character commands to their 8-bit ASCII equivalents; runs bib-
       tex(1) on the modified file; and finally moves the original auxiliary file back (overwriting the modified file).

       rubibtex assumes that the bibtex(1) database (bib) files are encoded with the KOI8-R encoding.

FILES

       basename.aux
	      LaTeX auxiliary file

BUGS

       None known, but report any bugs found to the authors.
