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
Source: LFS - Host System Requirements
This is a globbing wildcard pattern. It causes the shell to expand the line to
for lib in libgmp.la libmpfr.la libmpc.la; do
# ...
done
More on shell expansion and wildcard patterns: http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_03_04.html
Taking the first example from there, you can try the effect on the command line yourself:
$ echo sp{el,il,al}l
spell spill spall
