Code:
var=expdp_SDW_MSTR_VMDB.par
newname=${var%%par}log

Another approach
Note the use of the $ with the par$ in the sed command; this means to grab the text at the end of a line. Hence, the command did not change the par earlier in the text string.
Code:
> var=expdp_par_SDW_MSTR_VMDB.par > var2=$(echo $var | sed "s/par$/log/") > echo $var2 expdp_par_SDW_MSTR_VMDB.log
