You didn't say how it didn't work. I created a file junk1:
[linush at lh4 ~]$ cat junk1
/usr/bonsaitools/bin/perl
/usr/bonsaitools/bin/perl
/usr/bonsaitools/bin/perl /usr/bonsaitools/bin/perl
Then I copied and pasted the exact command you gave above:
[linush at lh4 ~]$ sed 's/\/usr\/bonsaitools\/bin\/perl/\/usr\/bin\/perl/g' junk1
/usr/bin/perl
/usr/bin/perl
/usr/bin/perl /usr/bin/perl
It appears to work just fine. Are you aware that sed will not make
changes to the file, but rather sends the updated contents to stdout
unless you use -i?
