I reading LSF and saw some operation, description one i am not found.
Please tell me what this means:
lib{gmp,mpfr,mpc}.la
Full code listing:
cat > library-check.sh << "EOF" #!/bin/bash for lib in lib{gmp,mpfr,mpc}.la; do echo $lib: $(if find /usr/lib* -name $lib| grep -q $lib;then :;else echo not;fi) found done unset lib EOF bash library-check.sh

$ echo sp{el,il,al}l spell spill spall
