Subject: how to use sed
Sorry to bother you with this but I want to know. I tried to use sed to change the perl path of my cgi scripts in a directory. from /usr/bonsaitools/bin/perl to /usr/bin/perl #sed 's/\/usr\/bonsaitools\/bin\/perl/\/usr\/bin\/perl/g' *.cgi it didnt work so I changed every thing one by one but I know sed can do the job for me. can someone teach me that? thank you
Using sed (clunky):
[thomas.cameron@mail ~]$ cat foo #!/usr/bonsaitools/bin/perl [thomas.cameron@mail ~]$ sed "s/\/bonsaitools//" foo #!/usr/bin/perl [thomas.cameron@mail ~]$ sed "s/\/bonsaitools//" foo > zzz [thomas.cameron@mail ~]$ mv zzz foo [thomas.cameron@mail ~]$ cat foo #!/usr/bin/perl
Using perl (better):
[thomas.cameron@mail ~]$ cat foo #!/usr/bonsaitools/bin/perl [thomas.cameron@mail ~]$ perl -pi -e 's/\/bonsaitools//' foo [thomas.cameron@mail ~]$ cat foo #!/usr/bin/perl
Certainly there are different/better ways.
