Regular expression API

1
Regular expression API

• POSIX regular expressions in Libc
• Just like in grep and egrep similar to Perl and
  .Net
• Incredibly useful
• A sort of inverse function to Format()
• Great for configuration files
• Can handle dates that StrToDate cant
• Like 29-Oct-02, for example

2
Security

• File permissions are based on user and group
• Finer-grained than Windows a file may be
  read-only to you but not to me
• Root user can do everything
• Admin powers arent as separable as on NT

3
Shell scripts

• Much more capable than batch files
• Can loop and test
• Read and write files
• Can do arithmetic and string manipulations
• May be better to call glue scripts instead of
  multiple Linux commands
