Body
I spent a whole day trying to process some files with backslashes and spaces inside their names. No matter what I do awk (gawk) refuses to print backslashes: <pre><code>echo "this/pathname/contains/spa ces/and/back\\slashes" | xargs -d'\n' -n1 -I{} bash -c 'echo "{}"; echo whatever | gawk "{printf {}}"' this/pathname/contains/spa ces/and/back\slashes gawk: {printf this/pathname/contains/spa ces/and/back\slashes} gawk: ^ syntax error gawk: {printf this/pathname/contains/spa ces/and/back\slashes} gawk: ^ backslash not last character on line </code></pre> This didn't work since the backspace gets directly into awk code. <pre><code>echo "this/pathname/contains/spa ces/and/back\\slashes" | xargs -d'\n' -n1 -I{} bash -c 'echo "{}"; echo whatever | gawk "{printf \"{}\"}"' this/pathname/contains/spa ces/and/back\slashes gawk: warning: escape sequence `\s' treated as plain `s' this/pathname/contains/spa ces/and/backslashes </code></pre> This worked, but awk eats the backslash. As you can see above, echo prints it but awk doesn't. <pre><code>echo "this/pathname/contains/spa ces/and/back\\slashes" | ./escape.sh | xargs -d'\n' -n1 -I{} bash -c 'echo "{}"; echo whatever | gawk "{printf \"{}\"}"' this/pathname/contains/spa\ ces/and/back\slashes gawk: warning: escape sequence `\ ' treated as plain ` ' gawk: warning: escape sequence `\s' treated as plain `s' </code></pre> Next I tried escaping the filenames using escape.sh <pre><code>#!/bin/bash xargs -d'\n' -n1 -I{} bash -c 'echo $(printf "%q" "{}")' </code></pre> Now there's a double backslash in there but awk still complains. <pre><code>echo "this/pathname/contains/spa ces/and/back\\slashes" | ./escape.sh | xargs -d'\n' -n1 -I{} bash -c 'echo "{}"; echo whatever | gawk -v VAR=$(printf "%q" "{}") "{printf VAR}"' this/pathname/contains/spa\ ces/and/back\slashes gawk: ces/and/back\\slashes gawk: ^ syntax error gawk: ces/and/back\\slashes gawk: ^ unterminated regexp </code></pre> Now awk said some nonsense about some unterminated regexp. Any ideas? Thanks!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
