发帖数: 757 | 1 Can someone help me out on this? I have a executable c program that will
give a sentence like this:
Quantization error of era_adv_jfm/era_tot_adv_high with map era_adv_jfm/high
.map is 860.665649 per sample (632 samples)
What I need is the first numeric value so that I can use it in a schell
script.
Thanks. |

string is easy, just parse it and use isdigit() to check on each char

发帖数: 757 | 3 Can you be more specific? I am really a newbie about shell script. I stored
the output sentence into a file and now I ONLY need to know the value of the
numeric part. Thanks again.

要不用awk，如果数字位置固定
awk '{print $9}' < input

发帖数: 757 | 7 I have to bother you guys again, e.g, in my shell script, I want to pass the
numeric value to a variable. I did this:
#!/bin/sh
...
value = `awk '{print $column} < input `
...
It seems there is something wrong with this, when I used echo to test the
passing, the result from awk is not passed to value. Could someone tell me
what was wrong in the statement. Thanks again.

发帖数: 5 | 8 what shell, (t)csh or bash ...
the
$column in shell is different from $column in awk
for bash(no space allowed around the '='):
value=$( awk -v col=$column '{ print $col }' < input )
