File size: 5108 byte(s)
fixed multi-word search (so that "apache server" [with quotes] will work same for
apt-cache search and apt-iselect as opposed to just apache server [without
quotes])

8     # 2003-08-02 first version
9     # 2003-08-03 using mktemp to create temp files, auto-install iselect
10     # 2003-08-04 catch signals so temp files are not left behind, added
11     # enter new search at end of results, autoconfig
12     # 2003-08-06 changed delimiter to \s/ to prevent conflict with e-mails
13     # 2003-08-15 automatically run apt-get update if there is no package list
14     # (e.g. changing apt/sources.list without update), cut lines
15     # to 80 chars before sending to iselect (bug workaround)
16     # 2003-08-31 changed delimiters to {}, q on detail page brings back list of
17     # results, highlighted search word(s) in package details
18     # 2003-09-01 changed script to work with any POSIX complient shell, and not
19     # only bash (thanks to Ulrich Doehner for bug report and
20     # suggestions), added support to use su if sudo is not
21     # installed, fixed search with more than one word (thanks
22     # to Tobias Gruetzmacher who reported this bug)
23     # 2003-09-04 moved do_sudo before first call (fixes bug when trying to
24     # install iselect)
25 dpavlin 4 # 2003-10-09 allow multi-selection of packages to view details
26 dpavlin 3 # 2003-11-13 fix for RedHat 9.0 mktemp bug suggested by Dobes Vandermeer
27 dpavlin 4 # 2004-07-27 allow multi-selection of packages to install
28 dpavlin 9 # 2004-12-04 add quick install options
29     # 2004-12-06 fixed multi-word search

31     # I know it's ugly, but it's still faster than aptitude :-)
32     #
33     # It will automatically use sudo if installed or require user to enter root
34     # password when needed. It will also install iselect deb package
35     # if it's not already there.

38     # 1020 and maximum length of all results is 1048576 bytes
