78 or: $0 [-v] -f F*EX-URL(s) e-mail-address
82 options: -v verbose mode
84 -s save to filename (-s- means: write to STDOUT/pipe)
85 -o overwrite existing file
86 -k keep on server after download
87 -X do not extract archive files or autoview file
88 -d delete without download
89 -f forward a file to another recipient
90 -a get all files (implies -X)
91 -l list files on server
92 -i tag alternate server/account, see: $fexsend -h
93 -P use Proxy for connection to the F*EX server
94 -H show hints and examples
95 argument: F*EX-URL may be file number (see: $0 -l)
99 When you download a file with extension .jpg .gif .png or .tif an image viewer
100 will be started. This can be xv or xdg-open.
101 In $HOME/.fex/config.pl you can set your prefered autoview applications:
104 '\.(gif|jpg|png|tiff?)' => 'my_prefered_image_viewer',
105 '\.(avi|mp4|mov)' => 'vlc -f',
109 For HTTPS you can set the environment variables:
110 SSLVERIFY=1 # activate server identity verification
111 SSLVERSION=TLSv1 # this is the default
112 SSLCAPATH=/etc/ssl/certs # path to trusted (root) certificates
113 SSLCAFILE=/etc/ssl/cert.pem # file with trusted (root) certificates
114 SSLCIPHERLIST=HIGH:!3DES # see http://www.openssl.org/docs/apps/ciphers.html
116 You can set these environment variables also in $HOME/.fex/config.pl, as well as
117 the $opt_* variables, e.g.:
119 $ENV{SSLVERSION} = 'TLSv1';
