&lt;p&gt;&lt;b&gt;Pagină nouă&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Introducerea Datelor într-un Script ==&lt;br /&gt;
&lt;br /&gt;
Scripturile Bash pot citi date de la intrarea standard (stdin) folosind un simplu mecanism de citire. Aceasta este utilă pentru a prelucra datele transmise prin pipe sau pentru a citi din fișiere.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039; Exemplu de Script &amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
Iată un exemplu de script care citește date din stdin:&lt;br /&gt;
&lt;br /&gt;
 #!/bin/bash&lt;br /&gt;
 #&lt;br /&gt;
 if [[ -p /dev/stdin ]]; then&lt;br /&gt;
    while IFS= read LINE; do&lt;br /&gt;
        echo &amp;quot;Linie: $LINE&amp;quot;&lt;br /&gt;
    done&lt;br /&gt;
 fi&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Explicații&amp;#039;&amp;#039;&amp;#039;:&lt;br /&gt;
&lt;br /&gt;
Verificarea intrării standard:&lt;br /&gt;
 if [[ -p /dev/stdin ]]; then &lt;br /&gt;
Verifică dacă stdin este un pipe. Dacă da, scriptul va continua să citească datele.&lt;br /&gt;
&lt;br /&gt;
Citirea datelor:&lt;br /&gt;
 while IFS= read LINE; do &lt;br /&gt;
Utilizează un loop while pentru a citi fiecare linie de intrare. IFS= asigură că spațiile sunt păstrate.&lt;br /&gt;
 echo &amp;quot;Linie: $LINE&amp;quot; &lt;br /&gt;
Afișează fiecare linie citită.&lt;br /&gt;
&lt;br /&gt;
Terminarea blocului if:&lt;br /&gt;
 fi&lt;br /&gt;
Marchează sfârșitul structurii de control if.&lt;br /&gt;
&lt;br /&gt;
Permisiuni de Executare: După ce ați salvat scriptul, asigurați-vă că are permisiuni de execuție:&lt;br /&gt;
 chmod u+x readpipe.sh&lt;br /&gt;
&lt;br /&gt;
Rularea Scriptului: Pentru a rula scriptul, utilizați:&lt;br /&gt;
 ./readpipe.sh&lt;br /&gt;
&lt;br /&gt;
Utilizarea cu Pipe - Pentru a transmite date către script folosind pipe, rulați:&lt;br /&gt;
 cat /etc/passwd | ./readpipe.sh&lt;br /&gt;
Aceasta va citi conținutul fișierului /etc/passwd și va afișa fiecare linie precedată de textul &amp;quot;Linie:&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Concluzie&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
Această metodă de introducere a datelor într-un script este foarte puternică, permițând prelucrarea datelor din diverse surse și este frecvent utilizată în scriptingul shell pentru a automatiza sarcini.&lt;br /&gt;
